Most ammo made for military calibers , but by different makers or countries have similar but not identical dimensions . Just compare WWI Brit .303 to US made .303 . German 7.92 x 57 mm was made with two different neck dia and three different bullet dia ,but all will fire in any German military rifle Gew-98 and up . Romanian made 7.92 x 57 mm is different in several ways than Yugo made , but both still fire in each others guns .
