Most firearm owner's manuals cover magazine maintenance. It isn't always necessary to disassemble the entire magazine for cleaning after every range session, but it is necessary to wipe the follower and lips with a cotton patch or cloth after every range session.
The 7.62x39 was not developed for sniper work. Longer cartridges such as the Soviet 7.62x54 were developed for precision work and mimic our 30.06 and .308. The 7.62x39 is a relatively short cartridge case, but packs an effective punch.
Dep. Jennifer Fulford never expected the assailant's 9mm bullet to rip through her nerves, disabling feeling in her fingers and causing the loss of use of her entire dominant hand. Fortunately, she was not out of ammo; she performed a one-handed reload with her weak (non-dominant) hand, as she had learned.
