I use the Dead Centers in 2 of my guns. the 45/50 260 gr and the 40/50 240gr. Both shoot excellent groups and good performance but if you have a tight bore you will find the standard orange sabot very difficult to load. I always liked the lead bullet ,so that is one reason i like them. I have killed more deer though with shockwaves and barnes TMZ's. dead centers are a little expensive for a lead bullet, but they do shoot good
