I have a 22 bolt action rifle and scope and a 6.5 284 model 7 bolt action rifle. The 22 can shoot 1 inch groups at one hundred yards with thunderbolts. I used those to kill a grondhog. It went in one ear and out the other. The 6.5 can shoot half inch groups at one hundred yards. I used it on my first deer. It knocked her right off her feet. :sniper: :gun4:
