Iam a bit surprised to find so called experienced deer stalkers advocating the use of 70 and 80 gn bullets. Ok if your spot on range and angle wise you have a kill if not the consequences can be horrendous!! Bullet blows up on impact, huge surface wound, long agonising death for beast. People in the know stipulate 100 gn bullets for medium to large deer , they are right.!!!Roe can be killed cleanly with .22 centre fires if you are a marksman.
