BUY Federal Premium Power-Shok 7.62x39mm 123Grain
Federal Premium Power-Shok 7.62x39mm 123Grain round is a rimless bottlenecked intermediate cartridge of Soviet origin. The cartridge is widely used due to the worldwide proliferation of Russian SKS and AK-47 pattern rifles, as well as RPD and RPK light machine guns. Shortly after World War II, the AK-47 was designed, later becoming the world’s most widespread military-pattern rifle. The cartridge remained the Soviet standard until the 1970s. It was largely replaced in Soviet service by the 5.45×39mm cartridge, which was introduced with the new AK-74 rifle, and continues in service with the modernized current-issue Russian Armed Forces AK-74M service rifle, as well as the AK-12 rifle. In the 21st century the 7.62×39mm remains a common service rifle chambering, including for newly developed rifles like the AK-15. Buy Remington Core-Lokt 7.62x39mm 125Grain ammo in-stock now!!.
After more detailed testing theFederal Premium Power-Shok 7.62x39mm 123Grain results became available, starting in 1947 the cartridge was tweaked by the Ulyanovsk Machine Building Plant to improve its accuracy and penetration. Initially, the boat tail had been omitted because the Soviet designers had assumed (incorrectly) that it would only make a difference at long ranges, when the bullet became subsonic, and the accuracy of the intermediate cartridge at these ranges was considered inconsequential. However, further testing showed that the boat tail improved accuracy even at shorter ranges, where the bullet was still supersonic. In order to maintain the overall mass of the bullet, after adding the boat tail, the ogival head section of the bullet was lengthened as well, making the bullet more streamlined overall. The maximum radius was now attained at some 15.95 mm from the tip and the overall length of the bullet increased to 26.8 mm. In order to preserve the total length of the cartridge, the case sleeve was shortened to 38.7 mm (and by rounding it is customarily referred to as 7.62×39.) Additionally, the new bullet had a core made of lead wrapped in low-carbon steel . The use of low-carbon (mild) steel was guided mostly by the desire to reuse some industrial equipment that was manufacturing the 7.62×25mm Tokarev cartridge rather than by bullet fragmentation considerations. This bullet was given the acronym “7.62 PS” (76.2 ПС). The “S” initially stood for “surrogate” (суррогатированная, surrogatirovannaya), but later the letter was taken to refer to the steel component (стальной, stal’noy) of the core, which accounted for about 50% of the core volume. The 7.62×39 cartridge equipped with the PS bullet finally overcame all objections of the GAU in mid-1947, when it was ordered into series production and given the index 57-N-231S. Field tests of the round and the new prototype AK-47 were carried out at the NIPSVO from December 16, 1947 to January 11, 1948.
