The head of a brass case can be work-hardened to withstand the high pressures, and allow for manipulation via extraction and ejection without rupturing. The neck and body portion of a brass case is easily annealed to make the case ductile enough to allow reshaping so that it can be handloaded many times, and fire forming can help accurize the ...
The aluminum sabot allows for a lighter projectile and hence a higher initial velocity. [ 6 ] The baseline design contains a propulsion system consisting of a metal case base, a combustible cartridge case, case adapter, nineteen perforated hexagonal JA2 propellant, a propellant containment device (cloth bag), and an M129 primer (all are ...

Headstamps were Warsaw Pact standard, with the contractor code at 12 o'clock and 2-digit year at 6 o'clock; brass-cased ammunition (Messing Hulse or Ms-Hulse) had an asterisk at 3 o'clock. Lots were made in blocks of 10; the first number before the slash was the sub-lot (1-10) and the number before the slash was the number of lots (1/9 is the ...

Instead, the propellant and primer are fitted to the projectile in another way so that a cartridge case is not needed, for example inside or ...
