I was working at the local community college with my associate Robart Schaefer.  We teach a firearms technology course there.  So naturally just about all conversations revolve around guns of one sort or another.  Robart mentioned he had seen a lot of Internet chatter about the 7.5 FK BRNO.  We had a good laugh when you brought up a post from a guy who asked if anyone had heard of the new company B_R_N_O?  He apparently have never heard of the famous city in The Czech Republic that has been producing firearms for at least 100 years.  Thus started a conversation with a lot of laughs that only a gun lover could appreciate.

First off, lets clear up some of the questions that pop to mind immediately.

  1. Is this company related to other well known BRNO companies from the Czech Republic?

Answer: No.  According to John Zent, Editorial Director for American Rifleman, this company has no connection the historical companies of the well known city of Brno in the Czech Republic.

2. What caliber is a 7.5 FK?


Answer: That would be a 30 caliber for the uninitiated to the Metric world of firearms.

3. What’s it look like?

Answer: A bottle-necked pistol cartridge.



Bullet Weight Velocity (fps) Energy (ft. lbs.)
5.7×28 40 gr. 1685 252
221 Fireball 40 gr. 3200 910
9mm Luger* 50 gr. 2000 454
460 S&W 200 gr. 2200 2150
30 Carbine 110 gr. 1990 967
7.62×25 85 gr. 1630 697

7.5 FK

100 gr.



*Specialty ammo from Liberty Ammunition

The first article about this cartridge that caught my attention was an American Rifleman story by John Zent titled, “Worlds Fastest Pistol– 7.5 FK Brno”.  This was where Robert and I started kicking cartridges back and forth.  30 Carbine was the first cartridge that really came to mind as the AMT Automag III had long ago had this slot pretty well locked up, if velocity was the only measure.

So is it the Worlds Fastest?  I guess you will have to break it down for yourself.

Most shooters will also look at bullet weight and therefore energy numbers to determine the true value of a cartridge.  Available guns, ammo and their price ranges also enter into the discussion.  Of course the inevitable question of revolver vs. semi-auto comes into play as well.  For me the question of stopping power is a bigger concern if this is going to be a self defense gun.

In the buzz around the 7.5 FK BRNO pistol is a point that will limit the number of buyers for this gun.  Prices in several articles have suggested that the gun will sell for around $5000.  If that is the case the audience for this gun will be small.

It’s highly likely that custom pistol makers will offer guns with custom barrels in the 7.5 FK chambering.  4D Reamer Rentals LTD (our sponsor) has already ordered in the reamers and gauges for this cartridge.

7_5 FK vs 30m1

30 Carbine vs. 7.5 FK

As of this writing the pistols and ammunition are supposed to be available from at least one U.S. retailer: https://luxuryfirearms.com/ They are holding the pricing pretty close to the vest, so most folks would infer that the high prices that have been reported in other articles are probably correct.

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

6.5 PRC from Hornady

6.5 PRC (Precision Rifle Cartridge) Hornady® introduced this new Short Magnum cartridge in the fall of 2017.  Gone are the days when such announcements were limited to the SHOT Show.

Factory ammo offerings in both a “Match” version (with 147gr ELD) and a “Precision Hunter” version (with 143gr ELD-X bullet). You can bet that in the future, Hornady will offer 6.5 PRC brass separately for hand-loaders, but it takes time to fill the pipe line with ammo and meet the initial demand.  6.5 PRC brass  is available right now from GA Precision at $86.00 per 100 cases. GA Precision’s George Gardner, who helped develop this cartridge, has posted: “It’s a non-rebated short mag based on a short RCM [Ruger Compact Magnum] case.”  It has 3-4 grains less capacity than the 6.5 RSAUM, so, the difference in ballistics will likely be 30-50 fps deficit as compared with the RSAUM.

The 6.5 PRC Match is aimed at the PRS (Precision Rifle Series) crowd and long-range tactical shooters. Hornady says the 6.5 PRC is, “designed to achieve the highest levels of accuracy, flat trajectory, and extended range performance in a sensibly-designed compact package. Utilizing moderate powder charges that result in repeatable accuracy, low recoil, and reasonable barrel life, the 6.5 PRC produces high velocities for target shooting with performance well beyond 1000 yards.”


New 6.5 PRC is a short magnum that requires a magnum bolt face.  It’s dubbed the “big brother” to the 6.5 Creedmoor, the 6.5 PRC fits in short or medium actions with a standard magnum bolt face (.532”).  Much of the Creedmoor appeal is it’s ability to function in the AR-10 platform.  The PRC will have non of that.

Ballistics charts from Hornady’s 6.5 PRC page shows a muzzle velocity of 2910 FPS. That’s not much better than a 6.5 Creedmoor (which can push 140s over 2800 fps), and the venerable 6.5-284 pushes similar bullets at about the same velocity as the new PRC.  The 6.5-284 utilizes a standard bolt face and you can get Norma and Lapua brass for it.  The PRC will work better than a 6.5-284 in a short-action magazine.  An awful lot of 6.5-284 fans put them on 30-06 length actions so they can seat the bullets out — that may be what Hornady is thinking with the new cartridge…

It looks like this is an attempt to attract some of the PRS crowd and help Hornady visibility in that highly popular arena.  Unfortunately for Hornady there is a trend among top PRS competitors toward smaller cartridge with less recoil. The benefits of less recoil are probably more important to those shooters than a flatter trajectory, which has a cost in both noise and recoil.

Reality is there is a market for everything, there will be some shooters who are very excited about this new offering.  GA Precision, Gunwerks, PROOF Research, Stuteville Precision and Seekins Precision are among those already chambering for this cartridge.  Truth be told, everything in the ballistic equation is a trade off.  A flatter trajectory and shorter time of flight have value too.

6.5 PRC Ammunition for Hunters — Also New for 2018
Hornady will also sell a version of 6.5 PRC ammo design for hunters, naturally that is about the bullet selection being appropriate for the application.  After looking this cartridge over and where it fits in the market place, it might have been better for Hornady to partner with Ruger and call it the 6.5 RCM, since that’s really what it is. This cartridge seems a little like the reason that Baskin Robbins has 31 flavors… try to please everyone and by so doing sell more product.

224 Valkyrie introduced by Federal Premium

Federal Premium® has announced introduction in time for the 2018 SHOT Show, a new cartridge designed to capture market in the popular MSR (Modern Sporting Rifle; Don’t you hate all these acronyms…) AR-15 platform.    The cartridge is design to capture the hearts of long-range precision shooters. The 224 Valkyrie produces flat trajectories, and  claims match-grade accuracy and supersonic velocities beyond 1,300 yards downrange.

“It beats the ballistics of all other MSR 15 cartridges, including the 22 Nosler, 223 Rem. and 6.5 Grendel. Plus, it offers comparable performance to larger rounds like the 6.5 Creedmoor, with roughly half the felt recoil—and at a more economical price,” explains Mike Holm, Federal Premium Centerfire Ammunition Global Product Lane.  “The 224 Valkyrie is based on a 30 Rem./6.8 SPC case necked down to .224 caliber,”

Shooters can review the technical specifications for the new round once it is approved by the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) which is expected in January at the 2018 SHOT Show in Las Vegas. At that time, information such as chamber specifications and cartridge pressure standards, proof pressure range and barrel length/twist recommendations will be communicated. Cartridge and chamber drawings will also be available soon after SAAMI approves the cartridge for standardization.

Testing conducted by Federal Premium engineers using 24-inch test barrels with a 1:7 twist revealed the 224 Valkyrie offers up to 128 inches less drop and 69 inches less wind drift (with a 10 mph crosswind) at 1,000 yards than other MSR 15 rounds. The new cartridge also offers significant advantages in velocity and energy.

The 224 Valkyrie will initially be available in four loads: 90-grain Gold Medal Sierra MatchKing, 60-grain Nosler Ballistic Tip Varmint, 90-grain Fusion MSR and 75-grain American Eagle TMJ. These proven Federal Premium bullet offerings provide options for long-range competitors, target shooters and hunters pursuing game from varmints up to deer-sized animals.

Federal created a new 90-grain .224-caliber Fusion bullet specifically designed for hunting deer sized game. In a test barrel the 90-grain Fusion exits the muzzle at 2,570 fps. This is going to be the thumper that P.O. Ackley pushed for 50 years ago. He stated back then that a “bullet of the CORRECT DESIGN AND CONSTRUCTION” was necessary for such cartridges.  Such bullets have not really been available until recent years.


224 Valkyrie ammo dimensions estimated from reamer print.

Federal Premium engineers designed the 224 Valkyrie for gas-driven MSR 15 actions, bu it’s also extremely effective from bolt guns. “You can also buy a new upper and use it with your existing lower. A gunsmith or other person trained in building MSRs can also make the necessary modifications. The easiest way for shooters to capitalize on the new cartridge is purchase a firearm from one of the many gun makers jumping on the 224 Valkyrie bandwagon,” says Holm.

Reloading data will be available in spring of 2018, when SAAMI releases it’s specifications.  Reloading die sets will be available from RCBS, and other ammo-building components will also be offered by several popular brands.

There are nearly 20 gun makers who have already started producing guns for the 224 Valkrie.  So if your hoping to try one out, it should not be hard to locate a gun in your local store before long.  4D Reamer Rentals LTD has already bought reamers and gauges for this new cartridge, in stock even before SHOT Show.

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


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

There is a review of the first two books on GunsAndGunsmiths.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.

Gun Safety and Children

The Month of June is:

Project ChildSafe’s Friends & Family Campaign

Just recently, I watched my adult son working with his 5 year old, my youngest grandson. He was showing him the single shot rifle built by me many years ago to teach my kids to shoot.  Of course it was cool to see the gun being used by another generation.  But even better, as my son spoke, I heard the gun safety speech that I gave him over 20 years earlier.  Now that is a legacy I am proud of.


My little grandson looked up into his Dad’s face and told him before his pop could even start the safety lesson, “You have to ask permission to touch a gun.”  That tells you that he has already learned a valuable gun safety lesson and knows it will be enforced.

During the Month of June the NSSF is sponsoring a campaign the teach gun safety to the next generation.  Get involved, go to their site and learn more about how you can help your family be safe with firearms.   Oh, did I mention there is a chance to win some cool stuff too?

Firearms have given me a wonderful career and hobby.  Respect for and attention to the safe use and handling of firearms insures the safety of the shooter as well as anyone in range.  Think, and be safe.

FVCC Announces registration for Firearms Program


Learn to build guns in a challenging program that really delivers.

Fall of 2017 the Firearms Technology Certificate program at Flathead Valley Community College is well established.  This will be the fourth year for this one of a kind program. This is the only such program in the United States and in 2016 was expanded to accommodate 16 full time students.

If you want to work in firearms manufacturing , this is the program.  Designed to help machinists gain skills and a “vocabulary” for the firearms manufacturing field, ultimately making them more employable.  The courses are constructed specifically to give the student a mechanical and ballistic understanding of firearms so that they comprehend how the parts they are building fit into the firearm system.  Issue like headspace, chamber pressure, accuracy and manufacturing tolerances are a major focus.

Employers have stated that this program give students the building blocks they need to be valuable in the firearms building business.

The instructor is quoted as saying, “This is a truly challenging and informative program. Students can come away with a wealth of knowledge and tools if they choose to apply themselves.  There is nothing more satisfying than sharing knowledge and giving someone with passion a leg up on the firearms trade.” Measure the bore to work with the reamer.

Gunsmith Writes About P.O. Ackley


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
