With greatest respect to both you and Mark, I'll mention that when you shoot a bullet that is bore sized, a bullet of the same weight is longer when it is a smaller diameter so it can be used in a sabot. All the more reason the longer bullet must fit snugly in the sabot, for perfect alignment, and be a firm fit going down the "wiped between shots" barrel (a needed hassle if using sabots with BP and most substitutes).My Patriot does not like sabots or maybe its just me. I cannot get a good group with my .45 cal with the barrel and i have tried alot of powder/bullet combinations with the light blue harvester sabot. However, shooting bullet to bore is another story. It loves the fury bullets, 265 gr. Stb and 275 black tip. It shoots moa with either at 100 yds. It really loves the 275 with 58 grains of vvn120, veggie wad, and fed 209a primer at longer distances, up to 300 yds. A real deer killing machine. Thank you Mark Woodman and team.
