Sometimes lower caliber bullets arent 1 shoting players by hitting brain, heart, head. Heart and brain should be places that need only 1 bullet to kill without armor. Higher caliber rounds should penetrate armor (helmets, plate carrier) and that should be main reason to use them. For now 5 shots to chest with M4 or 2 shots to head without helmet with mosin is way too much. Realism plz.
