Yes it does have an effect because I shot a guy with it once without stopping power and he didn't die. It was probably in the foot but still, no juggernaut either.
yeah bro i use my red barrret with claymores fragx3 and deep impact one hit kill even if its in the knees but i dont worry about especially since i got my red tiger in 1 hour in ground war. i have like 12 thousand headshots so yeah.
