I have decided I really need a new barrel. (I know I have said this before but this time I really am). I already have a 54cal so I do not need another and I am not going to get a 50cal. My mind is made it is a 58cal. GM or TC? I will mostly shoot roundballs but the TC would be nice because it is shorter and I could try conicals if I wanted. I am leaning toward GM. What do you all say?
