RE: powerbelt bullets
Seeing how you were 130 yards away, you shouldnt get any fragments. Usually this only happens when the deer are close. I know with 2 of the deer i shot with 120 and 150 grains, those were well over 140 yards and the bullets just blew right through them and didnt expand.
Lower your charge down to 100 grains, Use loose powder and hit them right behind the shoulder. Try not to hit them so high. Shot placement is the most important.
