these are what I have been shooting. Barnes 250 grain XPB all copper hollow point. They are also made for the .454 but since they are .452 diameter and cheaper then the Expanders I figured why not... So far they are doing a real good job but I have not had a chance to get any real distance with them other then 100 yards. They did well out to that point. I've been pushing them 110 grains of Goex 2f.
