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).

Chamberings: .222 Rem (1:14″) | .223 Rem (1:9″) | 6.5 Grendel (1:8″)
Specs: OAL 44.5 inches | Barrel Length 25.6 inches | 8.8 pounds (without optic)

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.”
