I have an old Huntsman in .45 with 1:56" twist. Accuracy was always fair but not outstanding. I stumbled upon an accurate load. I use Nosler 125 grain Jacket Hollow Points .357 caliber in a blue Hornady sabot with 80 grain of loose Pyrodex P grade. I get about 1 inch groups at 50 yards. I have not yet tried 100 yards. Thes ewere the first sabots to shoot well in this gun.
