If you really want traditional then the alower round ball twist which allows higher velocity with out blowing the patch would be closer and the advice on using a 54 cal is good it has a combination of caliber and velocity that no other caliber matches. Now if you are only going part way to traditional and are going to use sabots and bullets a 50 cal is best. If you find it fits you and can afford it a TC Renagade is an excellant choice but there is nothing wrong with the ones you are looking at either. Lee
