The 14.5×114mm (.57 calibre) 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, and 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 ...
I think "14.5mm" ought to direct you to this page, since that's what most people are probably looking for, and the average person doesn't know the full designation. If they'd like to read about the KPV machine gun or PTSR-41, or even the super-rare "14.5mm JDJ", they can find a link to it here.
By necking down the cartridge 14.5×114mm to accept .50 BMG, 12.7×114mmHL was created, with a muzzle velocity of 3,280 feet per second (1,000 m/s). MCR Horizon's Lord was also designed to be adaptable in comparison to other similar rifles.
The 14.5mm armour-piercing bullet has a muzzle velocity of 1,013 m/s (3,320 ft/s) and devastating ballistics. It can penetrate an armour plate up to 40 mm (1.6 in) thick at a distance of 100 m (330 ft). [4] In 1943 Simonov used a scaled-down PTRS-41 design for the SKS, that would accommodate the new 1943-designed 7.62×39mm cartridge.
All weapons in the ZPU series have air-cooled quick-change barrels and can fire a variety of ammunition including API (B32), API (BS41), API-T (BZT) and I-T (ZP) projectiles. Each barrel has a maximum rate of fire of around 600 rounds per minute, though this is practically limited to about 150 rounds per minute.

With 135 film cartridges, the DX Camera Auto Sensing code uses a 2×6 grid of rectangular contact areas on the side of the metal cartridge surface; these areas are either conductive (bare metal) or non-conductive (painted). The left-most area of both rows (with the spool post on the left) are common (ground) and are thus always bare metal.
The new video camera tube developed by Lubszynski, Rodda and McGee in 1934 was dubbed "the super-Emitron". This tube is a combination of the image dissector and the Emitron. It has an efficient photocathode that transforms the scene light into an electron image; the latter is then accelerated towards a target specially prepared for the emission ...
