Recently I discovered a T/C Hawken 50 cal sitting in a pawn shop. It appeared in rough shape, but they really wanted to get rid of it and we made a really good deal. Finish on the stock was rough, dented and such, but after stripping the poly off, doing a sanded finish and hitting the brass with blue black it lookes pretty good. I'm not real sure of the barrel and I'm thinking of replacing it with a drop in from Track of the Wolf. So, if you were going to use this for target shooting would you get a 45 or 50 cal?
