20 Nosler

Yes, it’s on the way…    How do we know?  Click here. It’s pretty obvious.   Well that and the fact that SAAMI has published the specifications already.  The same print from SAAMI comments that a 32 grain bullet will go 4100 feet per second (fps).

Like the 22 Nosler the 20 is based on the 6.8 SPC case or 30 Remington depending on how you view it.  They both have rebated rims so as to fit in a standard AR-15 Bolt face.

The 20 Nosler will have about eight (8) percent more case capacity by water weight than  the 204 Ruger.  So is the velocity claim of 4100 fps realistic?  On Nosler’s own pages they show the 204 Ruger doing that velocity with the same bullet, so I would say, sure, it just means you will have short barrel life if you load to that level.

It’s long been know that velocities approaching 4000 fps are hard on barrels, the throat is erodes much more quickly regardless of the bullet diameter.  I foresee the barrels for this caliber being chrome washed or Melonite® teated simply to increase barrel life.

The 20 Nosler might have some loading flexibility that the 204 does not in that if you loading for 3500 to 3800 fps there are probably a few more powders that will get there with the larger case capacity.  One thing I noticed in looking for comparisons, the 20 Nosler falls in its own class in terms of case capacity, the 20 BR has just a couple of grains less capacity, but it’s not designed for the AR platform.  The other popular wildcats in this general class either have a fair amount less capacity, or a lot more.  If for no other reason, this cartridge will have a following just based on the case capacity.

There is certainly no doubt, this will be a flat shooting varmint cartridge that will do the job in the dog town or out taking coyotes.22NoslerVs20Nosler

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

5.56 x 45 (Nato) vs. 223 Remington; The Ongoing Saga

The subject of 223 Remington vs. 5.56×45 (5.56 Nato) is a popular source of discussion.

Probably one of the best blog posts on this subject can be found at http://www.luckygunner.com/labs/5-56-vs-223/

One item this and most of the discussions seem to overlook is headspace.  Since this blog leans more toward gunsmithing subjects, I wanted make sure this subject was discussed.   I often hear from clients that the 5.56 and the 223 differ in headspace.  The truth is, when I checked the various gauge makers they are all working to the same standard.

Why is this important?

Mainly because educating the shooting public minimizes accidents and makes life easier for all concerned.  None of the articles I looked at mentioned headspace.  Most of the chamber dimensions being shared do not include headspace dimensions.  This may be in part because they are so hard to locate for the 5.56 Nato.

Forster Products publishes the data for their 5.56 gauges.  Minimum headspace (Go gauge) is 1.4636” according to their specifications with a tolerance of -.0003”.  With the Maximum (Field gauge) measuring 1.4736”; that’s 10/1000s of an inch longer than the go gauge.  Most No-go gauges would be set .004” to .006”  longer than the Go gauge.  The Pacific Tool & Gauge print shown here uses a Go gauge that measures 1.4636”.

5.56 Nato Print

Look at the Minimum Headspace dimension listed on this print, it is identical to the dimension used on the 223 Remington.

SAAMI specifications for the 223 Remington show a Minimum headspace (Go gauge) of 1.4636” identical to the military spec for the 5.56×45.  The Nato round is not a SAAMI cartridge, so they do not provide prints or specification for it.

My curiosity as to why so many shooters think there is a difference between the gauges for these two, led me to do an Internet search to see what people are reading.  I consider all material on the Internet to be of dubious quality until I can confirm the data through trustworthy sources.  What I found was interesting; you have to dig deep to find anything that pertains to headspace and the 5.56 Nato.

What is easy to locate are drawings which purport to show why the two cartridges are not the same.  The dimensions  they are concerned with mostly have to do with the junction of the body and shoulder plus the shoulder and neck.  In the real world the camming action of the bolt closing would be more than sufficient to deal with the tiny difference that might exist in the brass.  Frankly there is more variation in tolerances allowed that these drawings account for, in short, it’s all smoke and mirrors.

One Internet source shows the Military gauge .001” longer than is found in the prints mentioned above.  Even if that were the case, that is only 1/5th of the difference between a standard Go and No-go gauge for the 223 Remington.  To be totally clear, it would make NO difference.

Conclusion:  Headspace gauges for the 223 Remington and the 5.56 Nato are identical.  The differences between the cartridges has to do with case wall thickness and how they are loaded.  If you want to shoot either type of ammo in your gun, rechamber it to 223 Wylde.  The Wylde chamber is designed to work safely with both types of ammo.

Getting Ready for “This Season”

It’s that magical time of year when hunters start saying, “This Season” instead of “Next Season”.

Upgrade, try a new caliber.

Upgrade, try a new caliber.

Across the west every year when the big game draw results become public hunters start to plan for their fall trips.  Once you know the results of the draw it’s time to assemble the gear and goodies you will need for a successful hunting season.

The problem is eternal though, that for most sportsmen we are still fishing, boating, hiking, camping and doing all those summer time activities with family and friends.  It’s difficult to turn your attention to fall plans when you’re so busy having fun in the outdoors.

Doing just one small thing can greatly aid in your fall preparations and takes only a few minutes out of your summer.  Last season either you gun broke or you decided it needed an upgrade before next season.  Well, next season is now this season.  Grab that gun from the safe and get it to the gunsmith now.  You can avoid the seasonal rush and be much more likely to get your job done before the fall hunt is upon you.

Fall is just around the corner

Soon you will be glassing for that buck.

It takes time to get in parts or barrels to upgrade your firearm.  Leave time for the gunsmith to acquire the parts you want.  Many gunsmiths I talk to even offer specials this time of year to encourage bringing projects in early.

So drop your gun off now, so you can get back out there and enjoy the summer.  Then when fall hits you will have that new barrel, scope, stock, trigger or whatever you need to be more successful on you hunt this fall.

Now go have some fun!

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.

New Chamber Reamers for 2015

26 Nosler

Popular new Cartridge for 2014.

Shot Show is just a few weeks away, Fred Zeglin of 4D Reamer Rentals LTD heads to Shot each year to make sure he has all the new caliber offerings for his clients.  Last year is was the 26 Nosler and the 25-45 Sharps (SRC).

So far the information leaks about new cartridges for 2015 have been controlled, no sneak peaks at what is coming from the factories.  However, Fred says there are new wildcats getting some attention.

6mm Creedmoor has already been added to 4D’s list of reamers you can rent.  It looks like wildcats on the 26 Nosler case are what will be hot in 2015.  Those calibers will include:

  •  25 Nosler
  • 27 Nosler
  • 28 Nosler
  • 30 Nosler
  • 33 Nosler
  • 35 Nosler
  • 375 Nosler
  • 416 Nosler

All of these wildcats based on the 26 Nosler case will use the same headspace gauges, they are simply necked up, or in the case of the 25 necked down versions of the parent case.

6mm Grendel and 6.8mm Grendel are making waves too.  Both of these are based on the popular 6.5 Grendel.  If you’re a bolt action fan these cartridge are available in a configuration better suited to a bolt gun as the BPC (Borden Palmisano Cartridge) series, all using the same gauges.

Look for 4D Reamer Rentals to add all these reamers and more in 2015.
