Product Overview
DoubleTap Hunter 255-grain HCSW is a hard cast semi-wadcutter .45 Colt load made for hunting. DoubleTap loads it at standard pressure, which sets it well under the +P hard cast loads compared. At 975 fps it makes 538 ft-lbs.
From a 25-yard zero it is 1.9 inches low at 50, still carrying 917 fps and 476 ft-lbs there. Its estimated recoil of 15.0 ft-lbs in the same revolver is about 49 percent under DoubleTap +P 255-grain HCSW.
If you're cross-shopping, Underwood 225-grain Hard Cast WC is 75 fps faster from a bullet 30 grains lighter, with 13 ft-lbs more at the muzzle. Buffalo Bore Heavy 300-grain SJFP is the full-power end at 1,325 fps and 1,170 ft-lbs.
- Standard pressure, where DoubleTap +P 255-grain HCSW and Buffalo Bore Heavy 300-grain SJFP are both +P
- Far less recoil than the +P hard cast loads compared, which makes a long session possible
- Loses little energy out to 50 yards
- The least muzzle energy of the hard cast loads compared
- Underwood 225-grain Hard Cast WC is a touch faster from a lighter bullet for a touch less recoil
