Standard groove diameter of foreign military rifles in 7.62 x 39mm is .311", and most factory ammunition is loaded with bullets near that diameter. The Ruger Mini-30, the first U.S. commercial rifle to be produced in this caliber, has a groove diameter of .308". The design of it`s chamber throat enables it to handle bullets of .308" and .311" diameters.
Some say the 7.62 x 39mm is equal in power to the .30-30 Winchester but this is not quite true. Although heavier bullets can be loaded in this cartridge, velocity is quite low since it was designed to push bullets from 120 to 125 grains to just over 2300 fps. In other words, no 7.62 x 39mm load can equal the .30-30 when its loaded with a 170 grain bullet.
Some foreign made rifles in 7.62 x 39mm have a reputation for accidentally firing when the bolt slams forward against the cartridge in the chamber. Such rifles are for collectors only and should be deactivated by removal of the firing pin.
