I use a 45. cal. T/C Blackdiamond ML, I shoot 180 gr. Hornady jacketed solids whith a sabot backed with 2 50 gr. Pyrodex pellets ignited by Federal primers. I have been using this combo for about 5 years and have been having problems with bullet expansion. I have tried to tweak the load, tried different sabots, primers and powders (both pellets and granular). The combo I'm using performs great on targets (avg. 1.25" at 100 yds.) but bullet expansion is terrible on deer. I've narrowed the problem down to the bullet and am looking for anyone who uses a 45 cal. bullets other than hornady? Any advice?
