How to read it: filled circles are the near and far zero, where the bullet's path crosses the line of sight;the triangle is the peak (max ordinate). The shaded band is the 4" vital zone, ±2" either side of the line of sight. The dashed line marks the edge of the hold-dead-on window. The chart is zoomed to where the zero matters; the tables below run to 100 yards.

Product Overview
Buffalo Bore Heavy 300-grain SJFP is a jacketed flat nose .45 Colt load made for big game. Buffalo Bore calls the bullet a jacketed flat nose. At 1,325 fps it makes 1,170 ft-lbs.
From a 25-yard zero it is 0.9 inch low at 50, still carrying 1,184 fps and 935 ft-lbs there. Its estimated recoil of 34.9 ft-lbs in the same revolver is about 18 percent above DoubleTap +P 255-grain HCSW.
If you're cross-shopping, DoubleTap +P 255-grain HCSW is 125 fps faster with 20 ft-lbs more at the muzzle from a bullet 45 grains lighter. DoubleTap Hunter 360-grain HCSLD is 125 fps slower with the heaviest bullet in the caliber.
- A jacketed bullet, where every other hard cast load compared has bare lead at the nose
- Holds more energy at 50 yards than DoubleTap +P 255-grain HCSW
- Far more muzzle energy than DoubleTap Hunter 255-grain HCSW, the standard-pressure load of the set
- Loaded to +P pressure, so it belongs only in a revolver built for it
- About 165 percent more recoil than Underwood 225-grain Hard Cast WC in the same revolver
- DoubleTap Hunter 255-grain HCSW is the load for practice
