Even though isn't calibre 7,62mm higher then 7,5mm? I know its not much... and i will accept the fact, but calibrewise
it's 7.5×54mm so there's more powder behind the round and it's theoretically more powerful... I think
Interesting discussion. Wound Ballistics studies in the 1973-1976 era, plus practical firing rates and associated shot groups resulted in Army analysts classifying infantry small arms into 3 general catagories: High powered rifles ala NATO 7.62X51mm (typically heavier, longer barreled, higher recoil, with best slow fire (even bolt action) shot groups at 250m (to 450m); Intermediate powered and shorter bbl "assault rifles/carbines" (either shortened casing with rifle bullets ala 7.62X39mm, or smaller caliber, lighter bullets ala 5.53, with better (semi-automatic) rates of fire inside 250m (to 50m); and low powered shortest bbl submachine guns/machine pistols ala 9mm PB with least recoil and best fully auto shot groups inside 50m. BOTTOM LINE here is the distinct engagement range bands. HP rifles (no significant difference between bolt action/semi-auto/fully auto) can defeat the other type weapons (one on one) in open terrain affording greater than 250m engagements. Inside 250m, the AR/carbine is slightly better than a semi-auto or fully auto rifle. The SMG/MPs dominate inside buildings, heavily wooded terrain. and when intervisability is 50m or less.
A few side notes:
-Only snipers should engage targets beyond 450m
-Max effective range of ARs/carbines is ~375m
-Max effective range of SMGs/MPs is ~125m
-Theoretical weapon rates of fire are meaningless as long as they are at least 360 rounds per minute. Rates of fire greater than 600 r/m generally wastes ammo when shoulder fired.
-Practical fully auto rates of fire combine 3 to 5 round bursts with magizine size.
