Headspace Gauge Interchangeability App is Here!

Our friends over a 4D Reamer Rentals LTD have come up with a free app, yes its yours to use with no strings attached, none at all.

This app does what apps do best, provide a simple way to get the information you need and have it handy on your device/phone at all times.  Right now it’s available only for Android.

Two search methods are provided for the user. Results that are displayed are for cartridges that include the information you entered, so it matters what you type in.  It’s true, many gauges are able to correctly headspace more than one cartridge.  Knowing which ones is valuable information for the gunsmith. From the search results select the result that is closest to your desired caliber, each result will show the gauges that are fully interchangeable with that result.  If you do not see what you are looking for check the other options that appear in the result.  If no result appears, it is likely that your caliber of choice does not interchange with any other caliber, I.E. it has caliber specific gauges.

Many gauges will have “details” (information) available that should be helpful in selecting the correct gauges for your desired use.

With either search method when your receive “Compatible Results” similar to the screen shot below:

GaugeGuide App Screen Shot

The list of Gauges that Interchange is as complete as we have every seen.

Note that the list of “Gauges that Interchange” is a comma separated, continuous list. All calibers listed are interchangeable with the cartridge you searched.

The RENT or BUY buttons are used to place an order for the tools, if you need them.  You will be sent to the 4Drentals.com web site where you can order the tools you need.  The app can be found on Google Play, Click Here to see the page.

Search as much as you like, its free and informative!  Don’t take someones best guess what gauges you need, use a real data base that will tell you the truth and keep you safe.

429 Desert Eagle

Have you heard about the 429 Desert Eagle (DE)?

The 429 DE features 30 degree shoulder that it headspaces on and a neck long enough to properly hold and crimp a 240 grain bullet without set back under recoil. Based on the famous 50 AE cartridge, the 429 DE is made with Starline brass, and loaded by HSM in Montana with Speer and Sierra bullets.

Magnum Research is offering the 429 DE Mark XIX pistol, along with barrels and ammunition, for a
full product lineup in the recently introduced 429 DE cartridge. The 429 DE pistol has a stainless
steel slide, a stainless steel frame with Picatinny bottom rail, and a 6″ stainless steel barrel with
integral muzzle brake and black appointments. The pistol ships with a .50AE 7-round magazine and
has an MSRP of $2,143.

300 PRC Carves out a niche’ for Long Term Success.

Hornady has confirmed a report concerning the DoD’s decision: “The 300 Precision Rifle Cartridge (PRC), released by Hornady earlier this year, was tested and selected by the Department of Defense for its extended long range sniper program following a rigorous evaluation process that saw the new Hornady 300 PRC outperform the 300 Norma Mag as well as several other cartridges in testing past 2,000 yards.”

U.S. Department of Defense is adding the all-new Hornady 300 PRC (Precision Rifle Cartridge) to its arsenal. Last week the DoD awarded Barrett a contract to provide an undisclosed number of MRAD rifle systems chambered in 300 PRC.

More about the Hornady 300 PRC…

In keeping with current trends with new cartridges the 300 PRC is a non-belted magnum design. The 300 PRC is based on the .375 Ruger case.  Cases measure .532 at the base; this is the same as the .300 Winchester Magnum, so it will use a standard belted magnum bolt face.  There has been a wildcat version of this cartridge for many years, the 30/375 Ruger.  Another wildcat on the 375 Ruger is the 35 Miracle simply the 375 necked down to 358 caliber.

Our Sponsors over at 4D Reamer Rentals already have a couple of 300 PRC reamer and gauge sets on hand.

You can watch testing of the Hornady 300 PRC on BallisticMag.com.

75 Years of Reloading Tools: RCBS is that old…

Founded by Fred T. Huntington, RCBS was born in a small 12 by 6 foot room in the back of a laundromat in Oroville, California in the year 1943. In the early days following the attack on Pearl Harbor, there was a tremendous shortage of bullet-making equipment. Huntington had been shooting and hunting all of his life and wanted to make sure he would be able to continue pursuing his passion, even with limited products in his reach. The first dies were named Rock Chuck Bullet Swage as they were specifically designed for making jacketed bullets to shoot the Rock Chucks in the Western United States, providing the acronym RCBS that the company would become known by in later years.

In there early 80’s while I was in Gunsmtihing School we toured RCBS and Huntington’s Die Specialties.  Fred Huntington guided my group and showed us an original set of his bullet making tools on display in his store. Reloading dies were almost an afterthought, when starting out it was all about making bullets.

In 2015, RCBS became part of the Vista Outdoor portfolio. Continuing the tradition of releasing high quality products, shortly after this, RCBS released popular items to the market such as the Brass Boss, Vibratory Case Polisher, and the ChargeMaster Lite to customers.  “At RCBS, we continue to work hard to bring exciting products to our consumers,” said Global Product Director, Jason Slinkard. “Seventy-five years in business is a spectacular accomplishment. It’s an honor to work with a legacy brand known for dedication to innovation, accuracy and quality.”

With over 150 employees, RCBS still stands proudly in Oroville, California today. Consistently releasing new and innovative products, RCBS has the precision engineering to stake the claim of a true original.

Sierra Adds a 150 grain HPBT

150_264matchking

It’s a MatchKing® bullet actually introduced in October 2017 but is certainly being featured at the 2018 SHOT Show.  The popularity of 6.5 cartridges like the Creedmoor, 6.5×47 Lapua and 6.5×284 in all its numerous iterations will insure the sales of a new match bullet for Sierra.  At the time of this writing it appears Sierra is the only major bullet producer that offers a 150 grain bullet for the 6.5 bore.  This bullet will be best suited for cartridges with more case capacity, the 6.5-06 or the 6.5-284 will probably utilize it best.

MatchKing 6.5mm 150 grain HPBT (#1755).  Has a sleek 27 caliber elongated ogive and a final meplat reducing operation (pointing) to provide an increased ballistic coefficient (claiming over .700) for optimal wind resistance and velocity retention.  To ensure precise bullet to bore alignment, a unique bearing surface to ogive junction uses the same 1.5 degree angle commonly found in many match rifle chamber throats.  There is an interesting subject for a test; does matching the shape of the throat and bullet change the accuracy of any given bullet?

MatchKing® and Tipped MatchKing® bullets are not recommended for most hunting applications. Especially when we are talking about game animals of any size.  Match bullets are designed for accuracy and bucking wind over long range, but they are not designed to reliably expand.  Sierra makes GameKing® bullets for Hunters.

According to Sierra this bullet requires a barrel twist rate of 1 turn in 7.5” or faster.

Gunsmithing Student Handbook Series; Comes to the Market in Time for SHOT Show 2018

cover

The first book in the new series of Gunsmithing Student manuals is Chambering for Ackley Cartridges.  Fred Zeglin the author says, “I have been teaching gunsmithing for some time and with my experience in wildcat cartridges and dealing with clients it became painfully obvious to me that that material available to reloader, gunsmiths and the like are spread far and wide and do not tell the complete story of the mechanics of headspace in firearms.”

Zeglin went on the talk about the fact that Ackley Improved cartidges seem to receive the most mishandling both in the gunsmith trade and by reloaders who do not understand the simple headpsace method that P.O. Ackley set up very early in his career.

Ackley was no fool, he set up a method that is easy to use and will produce both safe and accurate fire-forming of ammunition.  There have probably been hundreds of articles written that tout the value of the Ackley Improved principle that allows the firing of factory ammunition for the parent case in the chamber of an Ackley Improved rifle.  Unfortunately, many folks refuse to read Ackley’s simple instructions so they end up trying to set headspace without proper understanding of the process.  Both professional and hobby gunsmiths are guilty of this.

Prove it you say…  OK, call any die maker and ask them for dies for an Ackley Improved cartridge.  They will ask you for a chamber or reamer print before they ship the dies.  Quality Cartridge is a maker of custom head stamped brass.  The owner Pete tells me he will not ship brass for Ackley designs unless he has fired cases from the clients gun, this is simply because of poor headspacing by gunsmiths, or the reloader who does not understand how his dies are adjustable.

In this booklet that kicks off the new series of gunsmithing instruction books, Zeglin clearly and without mincing words tells the reader how to correctly headspace any Ackley Cartridge.  It’s not a book about how to ream a chamber but rather about the finesse that should be applied during the process to insure accuracy and longevity of the firearm.

There is a book on how to ream a chamber that will be out in 2018.  That title is the third book in this series and Zeglin invited well known Bench Rest Gunsmith Gordy Gritters to co-author that book with him.    That will be the book you need you want to understand what it takes to make a rifle shoot, you know we all want those tiny little groups!  Watch for a follow up about that book here in the future.

coverThe second title in the series is coming out now as well, it is called, “Understanding Headspace for Firearms”  Where the first title is narrowly focused on Ackley designs this title will help the reloader and/or gunsmithing student to understand headspace no matter what firearm you are looking at.

Zeglin is pretty easy going about his work and tells us he fully expects to hear criticism over anything that was not covered thoroughly enough or heaven forbid, missed all together.  He says he expects to start the second edition for these manuals as questions start to roll in.

These titles are available from www.4drentals.com

Short Term Gunsmithing Program Returns to FVCC!

First class to be offered in the updated program of Short Term Gunsmithing classes will be Taming Wildcats, taught by Fred Zeglin at Flathead Valley Community College (FVCC) in Kalispell, MT.

This class will be offered during the Christmas Break, January 2018.  This is a one week class, non-credit.  Students learn the particulars of designing a wildcat cartridge.  Factors like the gun it will be used in, pressure, headspace, how to form brass are all taught.  Students also make reamer and reloading dies for the cartridges so they can experiment with the information they learn.Wildcat Cartridges by Fred Zeglin

If you are interested you need to know how to run a manual lathe and mill.  Fred has taught this class many times and students always come away surprised at how much they learn in just one week.  This class was the reason Fred wrote his book on Wildcat Cartridges.

This is just the first in a new Short Term Gunsmithing program to be offered in the summer of 2018 by FVCC.  Watch the Continuing Education pages for more classes soon.  This a  fun way for both hobby and professional  gunsmiths to build their skills and enjoy firearms even more.

Gunsmith Writes About P.O. Ackley

r3744_po-ackley_cvr-750

A new book from Gun Digest Media, P.O. Ackley: America’s Gunsmith by author and gunsmith Fred Zeglin; takes the most comprehensive look ever into the life and work of Parker Ackley, the eminent gunsmith, barrel maker, teacher and cartridge developer. The book is set for release the week of March 6, 2017

Ten years of extensive research highlights not just the history of cartridge and rifle development, but a never-before-seen look at a humble man who influenced nearly everything we know about shooting and ballistics today. Ackley’s ideas on reloading, rifle accuracy, safety, cartridge choice, and wildcats are just as relevant for modern “gun cranks” as they were in Ackley’s heyday.

This hardcover, 256-page study of P.O. Ackley’s work is the first in Gun Digest Media’s Heritage Series celebrating the iconic guns, designers and manufacturers who shaped today’s firearms landscape. The book is illustrated with never-before-seen photos from personal archives of Ackley’s friends, family, and associates. From the dusty, oil rag-covered machine shops of Ackley’s early years, to stunning modern-day firearms chambered in Ackley’s timeless wildcats.  A full-color center section brings the story to life.

From the Foreword of the Book

“It is a difficult task to write a book that is equal parts technical manual and biography, yet Fred Zeglin has done just that. Within the covers of this book you’ll find the history of P.O. Ackley, and a glimpse into the man’s life, as well as a comprehensive understanding of the cartridges that he left behind. And, as a wonderful bonus to those of us who still tinker with copper, lead and brass, there is a wealth of handloading recipes for the Ackley cartridges, using modern powders and projectiles, to allow today’s shooter to connect with the wildcatter of yesteryear.” Phillip Massaro

About the Author

Reloading A to Z, from AGI

Guest Blog By Jack Landis

Showing case changes

Explaining how cases are changed when fired.

AGI Tech Services
Manager and Editor, GunTech Magazine

One of the questions I have most often fielded from AGI students and prospective students over the last several years is; “When are you folks going to do a comprehensive reloading course?”

Well, the stars finally aligned and we convinced Fred Zeglin to take the few weeks he had off between the courses he was instructing and his latest writing projects to use his impressive knowledge of reloading and cartridge design to teach this course.

Fred has an extensive background as a professional custom gunsmith, cartridge designer, and author. His books Wildcat Cartridges, Hawk Cartridges, and his AGI instructional video course, Taming the Wildcat are well worth studying by students of the subjects.

This new course is almost eight full hours of the information any reloader needs to know. As he says in the introduction, “There is something for everyone here. If you’ve never handloaded, everything you need to know to assemble safe, effective handloads is here. If you’ve loaded for years, odds are you will still find out things you never knew, considered, or completely understood.” Let’s take a look at what’s actually under the hood . . .

Disk 1 – Brief History of Reloading: This is no exhaustive history of every step in the evolution of loading firearms and cartridges, but rather a concise explanation of how we got to what we actually do today.
Reloading Components: Here Fred shows the various types of cartridge cases, bullets, primers, and powders. He explains their differences and the reasons why those differences exist. Why are spritzer bullets pointed?
Why are some powders shaped like little rods?
Ignition Theory: What happens from the moment the firing pin strikes the primer to the exit of the bullet from the barrel is carefully explained and shown in drawings.
Pressure Curves: A PressureTrace Internal Ballistics System is used to show the real-time gas pressure rise and fall from primer ignition until the bullet leaves the barrel, approximately 1.5 milliseconds. Fred draws curves
which demonstrate what the pressure curves would look like in the Fred Zeglin, Cartridge Designer
case of a dramatic overload, high pressure caused by an over-length case, and powder detonation which can
occur if a very small charge of slow burning powder is used in a large case.
Resource Books: Fred explains why the Cartridge Comparison Guide belongs in your library as well as other books
that give you information on a huge number of cartridge’s dimensions, shapes, ballistics, and terminal performance. The reference books discussed will help you decide what cartridge you might want in your next gun.
Reloading Manuals: Reloading without these “must have” sources is like driving with your eyes shut, a real recipe for disaster. You need more than one so you can cross reference loading data to make sure the load you are
contemplating is safe.

Disk 2 – Developing a load plan: What IS a loading plan and why do you need one? Have you
decided what the load you’re thinking about creating is supposed to accomplish? Do you have a purpose for loading it? What is it? Is it reasonable?

Powder and bullets shown

Selecting correct components for your load plan.

He explains to you why you shouldn’t be “That guy” who just searches for the hottest published load for his cartridge and doesn’t “Waste time” with Starting Loads. “Hey, if it’s published it’s safe, right? These guys always leave a safety
margin, right?” Why you need to keep a complete notebook recording loads, velocity, accuracy, etc.
The Bench: Where should it be, how should it be constructed, how sturdy does it have to be, how high should it be, and why. Press and Die Set-up: Learn how to properly set up the dies, shell holders, and decapping pins from a two die set in your press.

Prepping the Brass: Cleaning, Reaming Inspection: Why you need to clean and inspect your brass, chamfer ream the case mouth and clean out the primer pockets.

PressureTrace Internal Ballistics System
What’s in a “Complete loading kit?” Fred opens a big box from Hornady that contains everything you need to load quality ammo, other than cases, primers, bullets, and powder. Why these make sense for the beginner.

Lubrication: Fred shows you several different methods and products to lubricate the cases prior to resizing, and
why you need to do it.
Full-Length Sizing Dies vs Neck Sizing Dies: Ever wonder what the hoopla about neck sizing from accuracy buffs is all
about? Fred explains why you might want to do it, what makes you able to do it continuously with some cases, why you’ll have to eventually full-length size, and how to avoid “Over-sizing.” Do you know what guns you should not only
never neck-size for, and moreover why you’ll need a “Small base” die? What IS a small base die?
Sizing the Cases: By this time, you will be all set to make those cases like new again.
Priming the Cases: Fred shows you four different priming methods, and why some are better than others in his opinion.
Measuring the powder: Several different scales are shown and how to set them up. After that Fred dips, throws, trickles, weighs, and finally stands and watches a machine do it all.

Disk 3 – Charging Cases: Now we actually begin to load cartridges. Attach the powder measure to the press, verify it is throwing the correct weight, adjust the die so the case is just partially re-sized, and dump the powder into the case. Watch Fred set-up the bullet seating die for no crimp, set the bullet on the top of the case and feed it into the die, adjust its seating depth, and . . . voila!! A real live reloaded round of ammunition made by your very own self.
Seating Bullets with a Crimp: Here you will learn how to set the seating die so it will crimp the case mouth into the bullet’s cannelure just as the bullet reaches the correct depth, and why and when you sometimes need to do this.
Using the Lee Loader: Robart Schaefer demonstrates the use of the basic Lee Loader. Many of we “Senior” reloaders started with one of these tools. It gives you everything you need to load one caliber of good quality ammo for ~ $28. Just supply brass, bullets, primers, and powder. The box holding the tools will fit in the back pocket of your jeans, assuming you don’t fill them as full as some of us.
Fred at the bench demonstrating proper die set up
Next up is Robart Schaefer again, this time with the Lee Hand Press. This is basically a bench type press that
you can use sitting in your La-Z-Boy while watching football. And I have. While it won’t full length resize large
cases, it will do everything else. I probably used it more than anything else with a Lee decapping die, got
my youngest to do a bunch too, and then primed those cases with a Lee Auto Prime. Yep, thousands of them. Got them both for under $50 more than a couple of years ago.
Reloading Cartridges with a Three Die Set-up: Fred explains the use of three die sets. The third die is used to bell the mouth of straight wall cases and pour the powder charge through into the case.
Annealing Brass: Working (sizing) makes it hard and susceptible to cracking. Heating it softens it again and allows more loadings. Fred shows how to do this and gives several alternatives and cautions.
Case Trimming: Here’s where you learn how to trim those over length cases back to the correct size with a couple of different tools and ways of measuring.
Additional Case Prep Procedures: Learn about vibrating, tumbling, and ultra-sonic case cleaners. Learn how and why we uniform primer pockets and flash holes.
Reloading Cartridges Using a Progressive Press: Fred demonstrates a progressive loading press, and describes what happens, and how, at each station.
Disk 4 – Tools and Accessories: Fred wraps up the cartridge reloading portion with a “Show and Tell” of some specialty tools that will make your reloading easier. Shown are extended shell holders to ease the loading of really short cases, a competition shell holder set whose heights vary by .002 inches to allow you to set the exact amount of case sizing you want, powder measure baffle and drop tube, and neck lubers for neck sizing. Specialty dies include neck sizing dies with interchangeable bushings to adjust neck tension, Lee Factory Crimp dies, in-line feeding and micrometer seating
dies, and bullet pulling dies. An impact bullet puller is demonstrated as well.

Bullet Casting: Robart tells us why we should consider casting our own lead bullets and shows what tools and equipment are needed for the process.

Lead: What kinds of lead alloys are needed, where to scrounge what you need, or buy it pure or ready alloyed
if all else fails. The characteristics of the various alloys are discussed and their uses explained.
Pouring Ingots: How and where to heat your lead safely, why and how to flux, and cleaning the dross off the top. It’s kind of cool to see the steel wheel weight clips floating on top of the lead. How to pour the cleaned and alloyed lead into
smaller, easily handled ingots . . . into what looks like corn cob shapes in a jello mold. Why you can never have water around hot lead.
Casting Bullets: Now we get down to actually pouring lead into the molds. How to tell by looking at the bullets whether the lead, mold, or ladle is too hot or cold. He pours from a ladle into the top of single and double molds, and from the bottom into a six bullet mold.
Testing Hardness: Here is a tool the tests the Brinell hardness of the cast bullets and explains how you can determine how hard they have to be based on the chamber pressure of the cartridge they are going to be fired from.
Sizing and Lubing Bullets: Why cast bullets need to be sized and lubed after casting, and how it’s done. What to use for bullet lubes is a choice made based on the bullet’s expected velocity The Lube Sizer Press: This press has a heating
element that heats the lube before it deposits in the lube grooves, seats a gas check, and sizes the bullet, all in one
smooth stroke of the handle.

Final Thoughts on Bullet Casting: Robart wraps up his discussion of bullet casting with a reiteration of why it’s a cool thing to do, and repeats the cautions earlier expressed. Have fun and be safe!

Epilogue: Fred closes by showing a bullet neck concentricity gauge and explains what it tells you and why it is important as a lead-in to a discussion of why learning even more advanced techniques can improve your abilities as a reloader and shooter. If you have never reloaded a single cartridge, you can do so with success and confidence after watching this video course. You will also be able to make informed choices on what tools and equipment will fit your needs and budget.

As a bonus, AGI put Darrel Holland’s Advanced Reloading Techniques course in the package too!

28 Nosler Announced at Shot Show 2015

During the first day of SHOT Show 2015 I swung by Nosler’s Booth.  GEDSC DIGITAL CAMERA

And what to my wundering eyes did appear, the 28 Nosler. That’s right Nosler is adding to their line-up.  The 28 and 26 Nosler utilize the same headspace gauges.

Talking to Mike Lake, who did the design work on these cartridges for Nosler, he stated that everything from 26 to 9.3mm have been registered and approved by SAAMI.  For now, Nosler is only bringing the 28 Nosler to market.

When asked why Nosler took all the designs to SAMMI now Mike said, “We were aware of the wildcats that have appeared on the 26 Nosler case.  So, it just made sense for us to get the dimensions for all the calibers completed and registered with SAAMI.”

The 28 Nosler according to Nosler’s new catalog will push a 160 grain bullet at 3300 feet per second (fps).  A 175 grain bullet will launch at 3125 fps.  In case you were wondering that is faster than the 7mm RUM with less powder.  How is that possible?  Pretty simple really, the 7mm RUM is very over bore, in other words it has too much case capacity for the 7mm bore.

Last years introduction of the 26 Nosler was met with great enthusiasm by shooters.  There is every reason to believe that even more shooters will like the 28 Nosler, 7mm cartridges in general are more popular the 6.5mm in the U.S.  Look for this to be a much discussed cartridge in 2015.

I talked to Pacific Tool & Gauge and 4D Reamer Rentals LTD.  PTG says the 28 is in production already and 4D placed an order for it as soon as the cartridge was announced.  4D also ordered reamers for all the Nosler designs registered with SAAMI.
