.45 Colt Trajectory Calculator

The .45 Colt is a classic big-bore revolver cartridge with roots in the Old West. With a 250-grain bullet at 860 fps and a 25-yard zero, expect about 2.6 inches of drop at 50 yards, 8.4 inches at 75 yards, and 17.5 inches at 100 yards. Muzzle energy runs 411 ft-lbs and stays above 345 ft-lbs at 100 yards—enough for deer at close range with proper shot placement.

Use the calculator to match your specific load. Click "Modify Calculation" to enter your bullet weight, muzzle velocity, and ballistic coefficient. Standard pressure loads run 800-900 fps while +P loads in strong revolvers push past 1,000 fps with heavy bullets. You can also factor in wind and atmospheric conditions.
