Claymore and sniper rifle damage and pistol damage

People are walking past claymores or only being stunned by them. Realistically if you walk in front of a claymore its going to blow your legs off. 

I get hit markers when hitting people in the head with a sniper rifle. Head shots with a sniper of any caliber would kill you because most snipers use ap rounds. 

Its dumb that I shoot someone in the face 7 times with a pistol and get hit markers but they shoot me with a shot gun or rifle they kill me.
