Believe it or not, here is a cartridge that makes a .338 Lapua Magnum look like a toy. The 14.5x114mm cartridge was designed as a MG and rifle-fired anti-materiel round. To translate from the metric system to caliber and inches, the round is a mammoth .57 caliber which measures 4.49 inches to the case mouth, and 6.13 inches overall. That jumbo-sized case holds a whopping 655 grains of powder. Commonly-loaded projectiles weigh 920-1030 grains. The 993gr armor-piercing projectile has a muzzle velocity of approximately 1006 meters per second (3300 fps) and can penetrate 30-32 millimeters of RHA steel at a range of 500 meters.
The top photo comes from Elardus De Lang, a Forum member who works at the Truvelo Manufacturers Armoury in South Africa. Elardus also provided an impressive video showing the massive 14.5x114mm being shot from prone with a Truvelo-built bolt-action rifle. Elardus tells us: “Here is a video, with a slow-motion ending, of our 14.5x114mm anti-materiel rifle being fired in our indoor testing facility. This caliber is a true beast! It propels a 993gr Armor-Piercing Incendiary bullet to 3300 fps, burning 480 grains of powder in the process. [This shows] that rifles of that power level can actually be shootable. The concussion indoors is something to experience……every shot feels like you are being punched in the face, and the heat from the muzzle flash actually hits you like a wave!”
14.5x114mm Cartridge Design and Dimensions
The 14.5×114mm has 42.53 ml (655 grains H2O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt action rifles and machine guns alike, under extreme conditions. Cartridges typically use lacquered steel cases, but some countries also use brass cases.
All dimensions are in millimeters (mm). Americans would define the shoulder angle at alpha/2, or 22.5 degrees. The common rifling twist rate for this cartridge is 455 mm (1:17.91″) with eight lands/grooves. According to official guidelines, the 14.5×114mm can handle up to 360 MPa (52,213 psi) piezo pressure.
14.5x114mm Cartridge History
The 14.5×114mm (.57 Cal) is a heavy machine gun and anti-materiel rifle cartridge used by the Soviet Union, the former Warsaw Pact, modern Russia, and other countries. It was originally developed for the PTRS and PTRD anti-tank rifles, but was later used as the basis for the KPV heavy machine gun that formed the basis of the ZPU series anti-aircraft guns that is also the main armament of the BTR series of armoured personnel carriers from the BTR-60 to the BTR-80 and for heavy anti-material sniper rifles. The cartridge was designed in 1939 and first issued in 1941.

CZ has a new rifle that should appeal to varminters and target shooters. The new CZ 527 Varmint MTR (Match Target Rifle) is designed to provide enhanced accuracy with a heavy-profile barrel and stock that works well from bench or bipod. The MTR features a fast Mini-Mauser action with a trigger that adjusts from 2.25 to 4.95 lbs (10 to 22 N).
Click above photo for full-screen image with legible notations.
We wish we could tell you how the CZ 527 Varmint MTR shoots, but this rifle is so new that test samples haven’t made it to the USA yet. Based on experience with other CZ 527 models, we would expect about 1.2 MOA accuracy with decent factory ammo. With handloads you might get closer to 0.7 MOA for three shots. Sorry no USA price is available yet. However, the older CZ 527 Varmint, with a lesser-grade stock, has an MSRP of $725.00, so we expect the CZ 527 Varmint MTR to retail for around $875.00. We note that the latest model CZ 557 Varmint with similar, ergonomic Turkish Walnut stock has an $865.00 MSRP as listed in the 2018 CZ-USA Catalog.
CZ 527 Varmint MTR Features:
— Match-type stock design with wider, straight fore-end for good tracking on front rest.
— Slanted buttstock toe to adjust height in rear shooting bag
— Match-type ergonomic grip design with palm swell
— High-quality Turkish Walnut wood with oil finish
— Adjustable trigger pull from 2.25 to 4.95 lbs (10 to 22 N)
— Detachable 5-round all-metal magazine
— Heavy-contour 25.6″ (650 mm) hammer-forged barrel with threaded muzzle
Here is the manufacturer’s product description: “Thanks to the tried and tested CZ 527 system, the rifle is comfortable, reliable and fast to control. The trigger pull and pull weight may be set in the range between 10 and 22 N. Crucial for the high accuracy is the thick-walled 650 mm long barrel with a target pattern muzzle end and a thread for the attachment of accessories. The ergonomic walnut stock in oil finish is suitable for hunting as well as sport shooting. All users will also appreciate the superb ballistic properties of the 6.5 Grendel cartridge.”

.009″ — The Record That Stood for 40 Years.
In 1973 Mac McMillan shot an amazing 100-yard, .009″ five-shot group in a benchrest match. The .009″ group was measured with a 60x microscope for verification. Mac McMillan shot the group using a handbuilt prototype McMillan rifle with an early McMillan stock.
Mac’s .009″ group was the “Holy Grail” of rifle accuracy. This .009″ record was considered by many to be unbreakable, a record that would “stand for all time”. Well, it took 40 years, but someone finally broke Mac’s record with an even smaller group. In 2013, Mike Stinnett shot a .0077″ five-shot group using a 30 Stewart, a .30 caliber wildcat based on the 6.5 Grendel. Stinnett’s .0077″ group now stands as the smallest 100-yard group ever shot in registered benchrest competition.* Read About .0077″ group HERE.
Stinnett’s success doesn’t diminish the significance of Mac McMillan’s .009″ group in the history of benchrest competition. For four decades Mac’s group stood as the ultimate standard of rifle accuracy*. For those of you who have never seen Mac McMillan’s .009″ group, here it is, along with the NBRSA World Record certificate. The target now hangs in the McMillan Family Museum.
*Somebody else might claim a smaller group, but unless moving backers or electronic targets were used, it cannot be verified. Moving target backers are used at registered benchrest matches to ensure that five (5) shots are actually fired in each group. That eliminates any doubt.

Registration is open for the 2018 Crosman All-American Field Target Championship to be held July 20-22, 2018 in upstate New York. The Crosman All-American Field Target Championship will be held once again at the Rochester Brooks Gun Club, 962 Honeoye Falls #6 Road, Rush, NY 14543. Visit the Crosman website for Match Info and Schedule, or go directly to the Registration Page.
The event runs under American Airgun Field Target Association rules. Competitors attempt to knock down a variety of steel targets set at distances ranging from 15 to 50 yards. “The Crosman All-American Field Target Championship is one of the must-attend events for Field Target airgunners. We will have every level of competitor from the novice just getting started, to the world class competitor”, says Mark DeBoard, Manager of Shooting Services for Crosman.
The three-day competition features multiple shooting matches including the main two-day rifle event. There are five divisions for competitors: Open, Hunter, WFTF, Freestyle, and Pistol. In addition to the main rifle event, this year will also feature a pistol match, the Quigley Bucket Match and the Pyramyd Air Gunslinger match. The Bucket match re-creates famous scene in the movie “Quigley Down Under” in which the lead character shoots a bucket at 700 yards. Here the distances are scaled down a wee bit (wink). Competitors, using iron sights only, get 5 shots at a 1.75″ bucket placed at 55 yards.
This 2013 Video Explains the Field Target Discipline and Air Gun Classes
“Spots are limited, so please register soon,” says Crosman’s Mark DeBoard. “Field target is a fun event for all skill levels. Participants will benefit by shooting alongside members of Team USA and other [top shooters] from across the country.
Tech Talk: Why the Big Side-Wheels on the Scopes?
Field Target rifles shoot pellets propelled by compressed air. These light-weight, low-BC projectiles drop very quickly, with a looping trajectory. In order to hit targets at distances out to 50 yards or so, you have to adjust your scope to compensate for pellet drop. But you can’t set the scope correctly without knowing the precise range to the target. This is the function of the big wheels on the side of the scope. Field Target Competitors use the parallax adjustment on high-magnification scopes to determine target range. The big wheel allows quick, yet precise parallax adjustment. Markings on the wheel show the shooter the scope settings required for the distance “dialed-in” via the over-size parallax wheel.

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 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.

The 43″-long interior will fit most ARs and many hunting/varmint rifles (measure your own rifle to make sure). The handles are convenient and beefy and the wheels make this case easy to move through airports and parking lots. This is a very tough, roomy case for the money. Dimensions: 43″ X 13″ X 5″ (Interior); 46″ x 16″ x 5.5″ (Exterior).
8. Midsouth — Hornady BTHP Varmint Bullets, $52.29 for 500

One thing that plays a major role in building an accuracy load is neck tension. I think a lot of reloaders pretty much take this for granted and don’t give that enough thought.
So, how much neck tension is enough?
Thru the years and shooting both a wide variety of calibers and burn rates of powder, I’ve had the best accuracy overall with .002″ of neck tension. Naturally you will run into a rifle now and then that will do its best with something different like .001″ or even .003″, but .002″ has worked very well for me. So how do we control the neck tension? Let’s take a look at that.
First of all, if you’re running a standard sizing die with an expander ball, just pull your decapping rod assembly out of your die and measure the expander ball. What I prefer is to have an expander ball that is .003″ smaller than bullet diameter. So for example in a .224 caliber, run an expander ball of .221″. This allows for .001″ spring back in in your brass after sizing, and still gives you .002″ in neck tension. If you want to take the expander ball down in diameter, just chuck up your decapping rod assembly in a drill and turn it down with some emery cloth. When you have the diameter you need, polish it with three ought or four ought steel wool. This will give it a mirror finish and less drag coming through your case neck after sizing.
Tips for Dies With Interchangeable Neck Bushings
If you’re using a bushing die, I measure across the neck of eight or ten loaded rounds, then take an average on these and go .003″ under that measurement. There are other methods to determine bushing size, but this system has worked well for me.
Proper Annealing Can Deliver More Uniform Neck Tension
Another thing I want to mention is annealing. When brass is the correct softness, it will take a “set” coming out of the sizing die far better than brass that has become to hard. When brass has been work hardened to a point, it will be more springy when it comes out of a sizing die and neck tension will vary. Have you ever noticed how some bullets seated harder than others? That is why.
Paying closer attention to neck tension will give you both better accuracy and more consistent groups.
