Solved from this product's advertised 1050 fps, 225gr bullet and G1 BC 0.130, with the sight 0.5" over the bore at standard conditions. Compare every zero for .45 Colt.
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
Underwood 225-grain Soft Cast HP is a soft cast hollow point .45 Colt load made for hunting medium game. The bullet is cast from softer lead than a hunting solid, with a hollow nose. At 1,050 fps it makes 551 ft-lbs, far past the rest of the loads compared.
Zeroed at 25 yards, it is 1.7 inches low at 50, still carrying 967 fps and 468 ft-lbs there. Its estimated recoil of 13.2 ft-lbs in the same revolver is the heaviest of the loads compared, about 36 percent above Fort Scott Munitions 225-grain TUI.
If you're cross-shopping, Fort Scott Munitions 225-grain TUI is 181 fps slower at the same bullet weight, with 174 ft-lbs less at the muzzle. Federal American Eagle 225-grain JSP is 190 fps slower with 369 ft-lbs.
- The most muzzle energy of the loads compared by a wide margin
- A soft cast hollow point, the only expanding cast bullet among the loads compared
- The fastest of the loads compared
- Exposed lead at the nose, which some ranges ban
- The heaviest recoil of the loads compared, well above Federal Champion 225-grain LSWCHP
- A hunting load among target and carry loads, so Fort Scott Munitions 225-grain TUI is the gentler choice at the same bullet weight
