dont let that artical scare you off. The best artical to go by is experience. All of us that muzzleload " in my family" Use powerbelts and all deer have been killed with one shot. Unless you count my brothers that took 2 shots. first hit its spine and the last shot was a lung shot that killed it. If you use the 245, my favorite shot is a double lung shot. Im sold on these, doesnt matter how broke i am, im sticking with them. Nothing that lives and breaths can survive with a 1/2" hole in its body.
