A Sarge in the Army (1969) told my Platoon " A well placed bullet beats 20 rounds on Full Automatic every time." Meaning if you hit the target every time, that is better than spraying the trees and missing 75% of the time. Gives you more bullets to fight with.
5 targets coming at you . . .20 rounds on full auto . . . average hits 5 . . . . killing hits 1 . . . . (done on a range at 25 yards and less) 2 arm hits, 2 leg hits, 1 chest hit.
"It is not the SIZE that counts, it's the way you use it."
