RDF Bullets from Nosler — High BCs and Uniform Meplats

Nosler RDF reduced drag factor match bullets PRS High BC uniform meplats

Nosler’s line of RDF™ (Reduced Drag Factor) bullets feature very high Ballistic Coefficients, hybrid-type ogives, and tight, factory-closed meplats. Nosler’s RDF bullets were designed to be very competitive match projectiles for their respective bullet weights. Now offered in four calibers, Nosler RDF bullets genuinely deliver excellent performance for the price. Shooters, particular PRS competitors, have found the RDFs deliver the flat trajectory and high BC necessary to reach the podium.

Nosler RDF reduced drag factor match bullets PRS High BC uniform meplats

Nosler is proud of its RDF bullets, which feature tight, uniform meplats: “Nosler knows what gives competitive shooters an edge, isn’t an edge at all. It’s a point. With the highest in-class Ballistic Coefficient and smallest, most consistent meplat, RDF is the flattest-shooting match bullet in its class. Now available in more calibers and weights, the RDF’s meticulously-optimized compound ogive and long, drag-reducing boat-tail make achieving peak accuracy a snap”.

Experience RDF, the Flattest-Shooting Match Bullet:

Current Nosler RDF Bullets:
• 22 Cal 70 grain — G1 Ballistic Coefficient 0.416 | G7 Ballistic Coefficient 0.211
• 22 Cal 85 grain — G1 Ballistic Coefficient 0.498 | G7 Ballistic Coefficient N/A
• 6mm 105 grain — G1 Ballistic Coefficient 0.571 | G7 Ballistic Coefficient 0.280
• 6.5mm 140 grain — G1 Ballistic Coefficient 0.658 | G7 Ballistic Coefficient 0.330
• 30 Cal 175 grain — G1 Ballistic Coefficient 0.536 | G7 Ballistic Coefficient 0.270

RDF bullets are also available in Nosler factory ammunition in a variety of popular cartridge types. Nosler factory ammo lets you spend more time at the range and less at your reloading bench. Look for RDF bullets loaded in Nosler’s “Match Grade” Ammunition. Below is the .264-caliber, 140 grain RDF loaded in 6.5 Creedmoor, a popular chambering for PRS and tactical shooters.

Lone Star ELR — World’s Longest Shot Challenge in Texas

World's longest Shot Challenge Bryan Litz Applied Ballistics Texas Valdina Ranch ELR Extreme Long Range

Story based on report by Paul Phillips of Global Precision Group
Extreme Long Range (ELR) shooting continues to evolve, with new forms of competition “pushing the envelope” of marksmanship (and ballistics) at distances out to 4900 yards (2.8 miles) and beyond. The latest big-time ELR shooting match was the World’s Longest Shot Challenge (WLSC) in Texas. This match was held at the Valdina Ranch, 1700+ acres of gorgeous hill country property, located about 1.5 hours west of San Antonio, Texas. The event attracted 28 shooters competing in four classes. Each competitor could be supported by a spotter and a wind coach, shooting as a three-person team.

Key “Take-Aways” from the 2018 WLSC Match:

1. Prototype Berger .375 Caliber Bullet is a Winner
The new .375 caliber monolithic Berger bullet designed by Bryan Litz was used by the first and second place finisher in the above .338 Caliber class. It performed great and the ultra-high BC was confirmed.

2. Team Applied Ballistics Dominated
The combined Applied Ballistics Team made first-round impacts at 1760, 2000, 2200, and 2400 yards. Also, 11 out of the 12 impacts total at 2200 yards belonged to Team AB. And Team AB’s Chris Palka had the top score overall, in his first-ever major ELR competition. That demonstrates how well the AB ballistics solutions work. By yardage, Chris recorded 68280 points total, as follows: 1760×6, 2000×10, 2200×9, 2400×3, 2680×4.

3. Got Doppler? Advanced Radar Technology for ELR
To shoot at these extreme ranges, you need rock-solid BC information on your projectiles. Luckily Applied Ballistics brought a Doppler Radar and allowed competitors to shoot their ammo to give them personalized ballistic information.

Top Shots By Class
Above .338 Non-Factory
(mostly .375 CheyTac)
.338 and under Factory
(mostly .338 Lapua Mag)
.338 and under Non-Factory
(mostly .338 Edge)
Chris Palka 68280 HIGH SCORE
Paul Phillips 57360
Chase Stroud 47520
Pete Contacos 44360
Paul Phillips 20080
Chris Wiencke 14160
Tim Seller 25760
Eddie 14560
Calvin 11200

NOTE: There was also a fourth class at the WLSC, the “Above .338 Factory Class” (.50 BMG) with Jay Divorsky scoring 14560.

WLSC Match Procedures and Scoring:
Competitors shot with time limits at each distance: 5 minutes to make 5 shots at each plate. Hits on steel scored points, with a big premium on first-round hits. The point values (for hits) were based upon standard ELR practice: 5 times the distance on the first shot, 4 times the distance on the second shot, and so on. In this ELR match each team may have three members: Shooter, Wind Coach, and Spotter.

Paul Phillips reported: “After drawing names randomly for shooting order, on Day One we shot 36″ metal plates at 1760, 2000, 2200, and 2400 yards. The second day was elimination day — you had to make impact on each target at least once to advance to the next distance. These targets started at 2680 ranging out to 4900 yards. We had winds from 4-8 mph on the first day and 6-15 mph on the second day which made it very challenging.”

Proof in the Shooting — AB Solvers and Berger Bullets
Bryan Litz of Applied Ballistics stated: “This event was a successful test of several new things. Berger’s prototype .375 caliber solid bullets worked well in numerous guns and tracked perfectly to the most distant targets. Radar measurements of these new bullets indicate extraordinary performance as well. The AB Team also had a couple new staff members shooting their first ELR competition (Chris Palka and Chris Wiencke) who both did well with Chris Palka actually winning the event. This match was a successful demonstration of the science of accuracy being used to put rounds on target. The thing about science, is that it works the same for everyone. The ballistic software and Custom Drag Model (CDM) data that we used to put first-round hits on targets out to 2400 yards is the same software that’s available to everyone in the AB devices (Kestrel, Sig Kilo, Garmin Fortrex) and Mobile Apps.”

The AB ELR Team dominated the Podium in the above .338 Non-Factory Class. Chris Palka was high scorer followed by Paul Phillips (Second) and Chase Stroud (Third). The top two finishers were using Applied Ballistic Weapon Division Rifles sending the new Berger .375-Cal solid bullets designed by Bryan Litz. The third place finisher shot a .375 CheyTac with 400 grain Cutting Edge Laser bullets.

In the .338 and under Factory Class there were mostly .338 Lapua Magnums. These .338s did very well and two out of the three shooters made it to the two-mile plate. The final standings in the 338 and under Factory Class: Peter Contacos (first), Paul Phillips (second), Chris Wiencke (Third). Both Paul and Chris were shooting 300 grain Berger bullets.

Title Sponsor ELRHQ, a McMillan company, brought tables full of gear. Everything was on display: scopes, bipods, mats, bags, triggers, actions, brakes, stocks, LabRadars, TargetVision target cams, and more. ELRHQ.com is a great one-stop online vendor with the latest and greatest gear for those interested in the ELR discipline and precision shooting.

The match was organized by Travis Walla who did a great job. The event ran smoothly and shooters say the Texas BBQ was great. Travis posted: “We had an awesome event, thanks to all of our sponsors that helped make this event a huge success. We also had a awesome opportunity for those that shot this match — they were able to shoot across the Oehler Research 88 and Applied Ballistics LLC radar at the same time out to 2400 yards on Saturday afternoon. Thanks again…”

Don’t Go Deaf — Understand Risks of Concussive Hearing Loss

Mark Kuczka Accurate Ordnance hearing protection dB noise muzzle brake PRS muffs earplugs concussion concussive hearing loss

Did you know you can damage your hearing even if you are wearing the best hearing protection available? Well, have you ever heard of concussion (or concussive) hearing loss? There is no amount of anything you can put in or over your ears to protect you from concussion loss. My audiologist explained to me the concussion comes through the facial bone structure and damages the ear’s tiny bones.

Editor’s NOTE: This may be the most important tech article we’ve run all year. It explains how you can suffer inner ear damage and hearing loss even if you use earplugs or muffs. Read that again — hearing loss even with typical hearing protection. This kind of concussive hearing loss can result from shooting with muzzle brakes in confined spaces. Using a suppressor (aka sound moderator) can reduce the risk of concussive hearing loss. You may not have the ability to use a suppressor, but this article explains how you should be more mindful of your hearing.

Why I Use a Suppressor (Preventing Concussive Hearing Loss)

Report by Mark Kuczka, Accurate Ordnance

It must have been the road noise. I thought I was having a hard time hearing my five year old daughter speaking to me on my cell phone because of the road noise. That old SUV was kind of loud inside. Until I switched the phone to my left ear and suddenly I could hear her just fine. Wait, what just happened? I moved the phone back to the right ear and there was that muffled voice again. That’s when I knew I had a problem.

“What?” Lots of us in the shooting community have lost some hearing along the way due to our time on the range or in the field. Those of us who hunt have certainly discharged a firearm or three without ear protection and without concern for our hearing. After all, it’s just one shot, right? How much can it hurt?

Actually, that one shot DOES hurt your hearing. Any sound over 140 dB is immediate hearing loss. It just happens to be killing a small amount of our hearing so most of us continued the practice without a care. Living with hearing loss now makes me wish I could go back 20 years and better protect my hearing. I can’t change what I did in the past, but going forward I can certainly do the most to protect the hearing I still have.

I decided to shoot about a year’s worth of matches with just braked rifles. That year is when I lost significant hearing in my right ear and some in the left. I’ve gone back to shooting only suppressed rifles whenever possible.

Mark Kuczka Accurate Ordnance hearing protection dB noise muzzle brake PRS muffs earplugs concussion concussive hearing loss

I shot my first suppressed firearm, a .22 LR pistol, in 2003. After a few rounds I wondered why everyone (who can do so legally) didn’t shoot suppressed? No one drives without a muffler. Why would you? Point is I immediately appreciated the hearing protection benefits of suppressors. That passion got me into the business of selling suppressors and it wasn’t long before I was one of the biggest retailers for companies like AAC, SWR, SilencerCo, Ops Inc. and others. [Editor: The author’s business, Accurate Ordnance, no longer sells suppressors. So this article is NOT a sales pitch. Mark just wanted to share his experience so others might protect their hearing.]

Did you know you can damage your hearing even if you are wearing the best hearing protection available? You’ve heard guys say, “I’ll wear plugs and muffs, so I’ll be just fine shooting that .50 BMG!” Well, ever heard of concussion (or concussive) hearing loss? Yeah, I hadn’t either. I’ll sum it up the way the last audiologist I spoke with about my hearing loss did – there is no amount of anything you can put in or over your ears to protect you from concussion loss.

A hand grenade went off right next to a buddy of mine. He lost some hearing as a result of the blast. No one is really surprised by that. I mean it is an EXPLOSION. It’s loud. Duh. But I had no idea the blast from a muzzle brake could basically hurt my hearing the same way. The doctor explained to me the concussion comes through the facial bone structure and damages the ear’s tiny bones. Same thing as what can happen through any TBI (traumatic brain injury).

Hearing loss diagram inner ear

I’ve owned quite a few different suppressors over the years and have shot just about everything out there. I’m still as big a fan as ever. However, I wanted to see if using a suppressor in PRS (Precision Rifle Series) and similar matches was actually a hindrance. Some people feel the added length and weight of a suppressor can make getting into some shooting positions slower or problematic. So I decided to shoot about a year with a muzzle brake instead of a suppressor. I sure regret that decision…

Getting Headaches at PRS Matches Was Warning Sign
It is fairly common in PRS matches to shoot through pipes, vehicles, inside “shoot houses” and around other obstacles that echo a rifle’s blast. I noticed I was starting to get headaches about halfway through a day of PRS match shooting. I knew the issue wasn’t hydration. I mean look, if you are peeing every other stage down at the amazing CORE range facility in mid-summer you are NOT dehydrated. So, what was causing the headaches? It wasn’t until I went back to shooting suppressed in those same environments that it became clear the little mini concussions from that muzzle brake was causing my headaches. And of course the doctors confirmed that.

Let me stop here and say I am NOT anti-brake. Muzzle brakes are useful tools and for some situations are the best tools. An aggressive brake can be more effective at reducing recoil than a good suppressor. A suppressor does add some recoil reduction, just not as much as most quality brakes. Don’t forget to factor other variables, such as caliber and rifle weight, into the equation though. For example, a 15-lb 6mm Creedmoor rifle doesn’t need much recoil reduction in the first place.

Mark Kuczka Accurate Ordnance hearing protection dB noise muzzle brake PRS muffs earplugs concussion concussive hearing loss

So, I started shooting matches long before the PRS even existed and always shot suppressed in those days. The suppressors made communication with a partner or RO easier and it was just a more pleasant shooting experience. On the recommendations of a few people I decided to shoot about a year’s worth of matches with just braked rifles. That year is when I lost significant hearing in my right ear and some in the left. I’ve gone back to shooting only suppressed rifles whenever possible and especially at matches. I’ve only once or twice found the extra length of the suppressor made it a little more inconvenient to run a stage, but not by much. Trust me, the points I missed were not because I took two extra seconds getting the muzzle in a port or window.

My hearing is something I value and will do everything to protect from this point forward. You’ll never again see me on a match field with an un-suppressed rifle. To me the minimal gains of running a braked rifle aren’t worth losing more hearing.

Choosing a Suppressor — What to Consider

Okay, so I have hearing loss that I can’t get back and realize I need to go back to shooting matches with a suppressor. But which one? I’ll still be shooting matches with custom fit plugs so I just need something to add a little recoil reduction and kill that concussion.

At our shop, Accurate Ordnance, we generally recommend direct-thread suppressor solutions to our customers. The main reason for that is all the problems we’ve seen with other fast-attach muzzle devices. It doesn’t take much tolerance stacking to result in accuracy issues. There are a few exceptions for us and the Rugged Suppressors products top the list. Since the Razor 762 uses a muzzle brake adapter on the rifle to attach the suppressor, I can use the same suppressor on my .223 Rem training rifle. My primary match rifles are chambered in 6mm Creedmoor and 6.5 Creedmoor and the muzzle threads on those is a standard 5/8×24. My .223 Rem training rifle has .5×28 threads on the muzzle, which is standard for that caliber. Thus, the muzzle adapter interface lets me share the suppressors between all the rifles. And on that .223 Rem training rifle I have the option of switching the end cap on any of the Rugged products to a .223 aperture size, which makes the suppressors slightly more sound efficient (meaning quieter).

Applied Ballistics Secures $1.3 Million U.S. Defense Contract

Applied Ballistics LLC CTTSO Extreme Sniper Strike Operations ESSO

We want to congratulate Bryan Litz and his talented team at Applied Ballistics LLC. We have followed Bryan’s career as a bullet designer, ballistician, author, software product developer, and ELR pioneer. His team leads the world in advancing the science of long range shooting. And it looks like all the hard work has paid off — Applied Ballistics has secured a major contract to develop extreme long-range sniper capability for the U.S. Military.

Applied Ballistics LLC, a Michigan-based tech company, has been awarded a $1,300,000 contract by the Combating Terrorism Technical Support Office (CTTSO) to execute Phase 1 of the Extreme Sniper Strike Operations (ESSO) project.

Phase 1 of the ESSO project is focused on advancing the predictive capabilities of modern ballistic solvers by performing Doppler radar measurement and modeling of current service rounds at Extreme Long Range (ELR) as a function of gyroscopic stability, and refining the models of secondary ballistic effects such as spin rate decay and spin drift at ELR. Phase 1 will conclude with the ballistic modeling enhancements being integrated into the existing Applied Ballistics ecosystem of electronic devices which are currently deployed by numerous U.S. and allied armed forces around the world. Phase 1 is scheduled for completion in late 2018.

Phase 2 of the ESSO project is a potential follow on (2019) that focuses on the development and fielding of an advanced ELR sniper rifle system designed to drastically increase first-round hit probability at ELR on man-sized targets. The Applied Ballistics Weapons Division is currently conducting research and development on weapons platforms, as well as new cartridge and bullet options, that will maximize ELR ballistic performance from lightweight, practical, magazine-fed systems.

Old Meets New — Modern Modular Chassis for Swiss K31

Sureshot Armament group SAG K31 modular tactical chassis

You’ve never seen a Swiss K31 like this before…

The Sureshot Armament Group (SAG) has developed a modular aluminum chassis for the vintage, straight-pull Swiss K31 rifle. This chassis transforms an old classic into a modern, fast-cycling tactical rig. The SAG Lightweight K31 Rifle Chassis is CNC-Machined from aluminum. Hard anodized, it weighs just 2 lbs. 13 ounces. It offers adjustable cheek piece and butt-pad, with a three-inch LOP adjustment range. Believe it or not, installing a vintage K31 into this SAG stock is an easy bolt-on process. No modification of the K31 action is required.

The chassis-builder SAG states: “The main idea behind the SAG Lightweight K31 Rifle Chassis was to give the shooter …ergonomics of a Tube-gun but with lines of the classic rifle. The chassis ‘wraps’ the shooter around the rifle, moving bolt operation under the shooters cheek to allow the marksman to maintain cheek weld during the whole shooting series.” The chassis design also allows a more forward optics placement for better eye relief.

About Switzerland’s Original Karabiner Model 1931 (K31)
The Karabiner Model 1931 (K31) is a magazine-fed, straight-pull bolt action rifle. It was the standard issue rifle of the Swiss armed forces from 1933 until 1958, though examples remained in service into the 1970s. It has a 6-round removable magazine, and is chambered for the 7.5×55mm Swiss Gewehrpatrone 1911 cartridge (aka GP 11).

Although the K31 is a straight-pull carbine broadly based on previous Swiss “Schmidt–Rubin” service rifles and carbines, the K31 was not designed by Colonel Rudolf Schmidt (1832–1898) as he was not alive in 1931 to do so. Mechanical engineer Eduard Rubin (1846–1920) was the designer of the 7.5×55mm Swiss ammunition for which previous Swiss service rifles and the K31 are chambered. The Karabiner Model 1931 was a new design by the Eidgenössische Waffenfabrik in Bern, Switzerland under Colonel Adolf Furrer (1873–1958). The Karabiner Model 1931 replaced both the Model 1911 rifle and carbine and was gradually replaced by the Stgw 57 from 1958 onwards.

PRS Launches New AirGun Series — Affordable Tactical Fun

Precision Rifle Series Tac Comps Tactical Practical GAP Air gun Airsoft PRASS Series

Practical/Tactical shooting disciplines such as the Precision Rifle Series are today’s fastest-growing forms of rifle shooting competition. More and more shooters are enjoying the fun of tactical-style matches shot “on the clock” from a host of challenging positions. PRS competitors must rapidly engage a number of reactive and steel targets, while shooting offhand, prone, behind barricades, off tripods, and from a wide range of other positions.

The popularity of the original centerfire PRS format, which now draws hundreds of competitors at major matches, spawned a PRS spin-off for rimfire shooters. A year ago, the Precision Rimfire Challenge (PRC) was launched. Modeled on centerfire PRS competition, the PRC is a new .22 LR rimfire shooting game. Call it “PRS Lite” — a practical-style, multi-stage match shot with .22 LR bolt-action and self-loading rimfire rifles.

With the success of rimfire tac comps, the PRS has decided it’s time for air-gunners to join the fun. Starting in May 2018, the PRS will offer airgun side-matches at the most popular PRS events, including the High Mountain Shootout (June), Heatstroke Open (July), and GAP Grind (October). Sponsored by AirGun WareHouse, the new PRS airgun side-matches will be run as a new, season-long Precision Rifle AirSoft Series (PRASS). Competitors can use a variety of pneumatic airguns from makers such as Beretta, Crosman, FN Airsoft, and KWA Airsoft.

“The Precision Rifle AirSoft Series (PRASS) is perfect for newcomers to the tactical game who want to start with a low-cost, ultra-safe competitive experience that still offers the look and feel of the PRS tactical lifestyle. It’s great for young people as well as individuals who may be wary of real firearms. This may prove ideal for Millenials.” — PRS Competition Committee

Precision Rifle Series Tac Comps Tactical Practical GAP Air gun Airsoft PRASS Series
If PRS (PR-“Es”) costs too much, try PRASS (PR-“Ass”), the AirSoft version. With AirSoft rifles costing less than $150.00, PRASS is way more affordable!

PRS Marketing VP Jeff Wilson expects the AirSoft Series to be a huge success: “We know that most purchasers of tactical-style rifles rarely, if ever, actually shoot their guns because it takes too much time to train, and the cost of ammo is prohibitive. In addition, many new shooters are sensitive to the noise and recoil of actual firearms. And, let’s face it, some guys want to look tough, but they’re really just weenies. Our AirSoft Series addresses all those concerns. The guns are inexpensive, the ‘ammo’ costs pennies, and the air is always free!” Wilson also noted that airguns provide an ideal introduction to the shooting sports for newcomers: “Airguns are easy to shoot, and they can be purchased without background checks or waiting periods. They are great starter tools for new shooters. You can experience our full PRS tactical lifestyle at a fraction of the price. While these days PRS is just too costly for many, PRASS will be affordable for all!”

The show starts off with legendary marksman, David Tubb, winner of 11 NRA National High Power Rifle Championships as well as multiple National Long Range championships. Kelly notes: “Our first guest, David Tubb, is arguably the … winningest, competitive rifleman in history. Trophies aside, though, David’s biggest contribution to our shooting sports is his innovative mind. The underlying essence behind his company, Superior Shooting Systems, is the continued advancement of the ‘human factor’ in the shooting sports.” During this segment David addresses many topics, including cartridge design (6XC and 6.5 Creedmoor), ballistics, Extreme Long Range (ELR) shooting, optics, stocks and more.

Kelly’s next guest is Regina Milkovich, the first woman in history to win a major practical/tactical precision rifle match outright. (Regina was the overall winner of the 2016 NorCal Tactical Bolt Rifle Challenge.) Regina has been successful in many disciplines, and is now active in the Precision Rifle Series (PRS). Starting at the 44:50 time-mark in the video, Regina shows off her current PRS rifle, chambered for the 6XC cartridge. It features a McMillan stock, Defiance Action, Vortex Razor Gen 2 scope, and Timney trigger. Tactical shooters will want to watch this segment. Regina reviews the many accessories she uses both on and off the rifle. She shows the support bags she favors and discusses how the right choice of equipment can help improve your scores.

224 Valkyrie SAAMI “Blueprint” Now Available Online

SAAMI .224 224 Valkyrie chamber cartridge blueprint specifications spec

Plan to buy or build a 224 Valkyrie rifle this year? Well now you can get the official specifications for the new 224 Valkyrie cartridge and chamber. The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI), has released its official 224 Valkyrie “blueprint” which you can now download for your records. SAAMI approved the Federal Premium 224 Valkyrie as an official new cartridge this past January. The 224 Valkyrie’s SAAMI standards documents are now published and available to the industry as a whole, as well as to the public.

SAAMI .224 224 Valkyrie chamber cartridge blueprint specifications specSAAMI allows free access to technical data and drawings for cartridge and chamber designs, which are posted in the Specifications section of SAAMI’s website. All cartridge and chamber drawing documents are contained within the ANSI/SAAMI Standards and can be found on www.saami.org. The New SAAMI Cartridge Cartridge/Chamber Designs for 224 Valkyrie can be viewed here: http://www.saami.org/PDF/224-Valkyrie-Introduction.pdf.

About the 224 Valkyrie Cartridge
Federal Premium’s 224 Valkyrie is based on a 6.8 SPC case necked down to 22 caliber. The Valkyrie has a shorter case than the .223 Remington (and 5.56×45 NATO). This allows you to load the longest, heaviest .224-caliber bullets and still feed reliably from an AR15-type magazine. The 224 Valkyrie offers flatter trajectories than other AR15 mag-friendly cartridges, including the 22 Nosler, .223 Rem, and 6.5 Grendel. With heavy projectiles, the 224 Valkyrie boasts impressive ballistics — it can stay supersonic past 1,300 yards. Plus it has roughly half the recoil of larger cartridges offering comparable ballistics, such as the 6.5 Creedmoor (see chart below).

SAAMI’s work creates standards for the cartridge, increasing safety, interchangeability, reliability, and quality for firearm manufacturers building rifles chambered for the 224 Valkyrie. Federal Premium Ammunition President Jason Vanderbrink notes: “SAAMI’s approval of the cartridge was a crucial step in legitimizing [the 224 Valkyrie] within the industry”.

The Role of SAAMI in Creating Uniform Ammunition Standards
SAAMI was founded in 1926 at the request of the federal government and tasked with creating and publishing industry standards for safety, interchangeability, reliability and quality, as well as coordinating technical data. SAAMI’s Technical Committee, which consists of firearm and ammunition industry experts, reviewed the 224 Valkyrie submission over a period of about six months. The official cartridge name, maximum cartridge and minimum chamber dimensions, pressure limits, test equipment, and other characteristics are all considered and scrutinized during the process.
