As civilians were receiving surplus SKS/ AK's in the early 1980's, American ammunition companies had to try and keep up with the demand for the 7.62x39mm. Generally used for plinking or target practice at first, the cartridge was really no stronger than the .30 carbine. Held true to Soviet standards, it was only loaded to half pressures, leaving plenty of room for improvement, although females and children apperciate the light recoil. Most military ammo was made of steel cases and are non reloadable. With brass reloadable cases and newer gun powders, this cartridge could go beyond varmit/ medium game, to larger ones like deer. Ruger chambered the Mini-30 in '87, and the M77 Mark 2 in '91 for the 7.62x39mm. Sako and a few others followed after that. Now, most American ammo manufactures offer this round in soft point bullets and non corrosive primers.
The # 4 black over green tip is a 194gr subsonic bullet for the PBS AKM silencer from 1965. This was a weapon that was based upon the sks action for fairly long range shots. Its missing 8gr powder charge. It was done away with after the Chinese bought a large amount of US silenced weapons on the black market in late '65. wolfgang
