Product Overview
DoubleTap +P 255-grain HCSW is a hard cast semi-wadcutter .45 Colt load made for hunting. The bullet is hard cast lead with a flat shoulder and no jacket. At 1,450 fps it makes 1,190 ft-lbs, the most of the loads compared.
Zeroed at 25 yards, it is 0.7 inch low at 50, still carrying 1,265 fps and 907 ft-lbs there. Its estimated recoil of 29.6 ft-lbs in the same revolver is about 30 percent under DoubleTap Hunter 360-grain HCSLD.
If you're cross-shopping, Buffalo Bore Heavy 300-grain SJFP is 125 fps slower with 20 ft-lbs less at the muzzle from a bullet 45 grains heavier. DoubleTap Hunter 255-grain HCSW is the standard-pressure version of this bullet weight, 475 fps slower.
- The fastest .45 Colt load in the caliber
- Far more energy than any standard-pressure .45 Colt load compared
- DoubleTap's +P loading of the same bullet it sells at standard pressure, for a gun built to take it
- Loaded to +P pressure, so it belongs only in a revolver built for it, and most .45 Colt revolvers are not
- About 124 percent more recoil than Underwood 225-grain Hard Cast WC in the same revolver
- DoubleTap Hunter 255-grain HCSW is the load for practice at this bullet weight
