The 7.62mmR is used in the AKM and other ex-Soviet weapon types, and is not compatible with the larger 7.62mm cartridge. The .50 caliber is a huge cartridge generally fired from heavy machine guns, but also adapted to a few models of powerful sniper rifles.

Ammunition weight

To determine how much a loaded magazine weighs, look it up on the table, rounding the number of rounds in the magazine up. Shotgun shells are a little heavier; use the weight value for one damage step higher.
