HSM's Cowboy Action 158-grain RNFP is a lead round-nose flat-point, the cowboy-action bullet shape, loaded to 840 fps and 248 ft-lbs. That makes it the hotter of the two cowboy loads on this page and the fastest lead load here apart from Sellier & Bellot. Power factor is 133, which is 28 over the IDPA stock-revolver floor of 105 and 13 over the 120 USPSA revolver-minor floor, real margin in either game. From a 25-yard zero it drops 2.7 inches at 50 yards and 18.4 inches at 100, arriving at 804 fps with 227 ft-lbs and then 771 fps with 209 ft-lbs.

Black Hills Cowboy 158-grain CNL is the direct rival at 800 fps and 225 ft-lbs, 40 fps and 23 ft-lbs behind with about 8 percent less recoil energy in the same revolver and 2.0 inches more drop at 100 yards. Federal American Eagle 158-grain LRN gives up 70 fps and 40 ft-lbs and recoils about 13 percent less. Remington UMC 158-grain LRN and Magtech 158-grain LRN mark the mild end at 755 fps and 200 ft-lbs, about 16 percent less recoil and 4.5 to 4.7 inches more drop at 100 yards. Sellier & Bellot 158-grain LRN is the only lead load above it, at 997 fps and 349 ft-lbs with about 32 percent more recoil energy.

Buy this for cowboy-action matches and steel where you want a lead load with a clear margin over both power-factor floors, or as a practice load with more push than the 755 fps loads without going to +P. Some indoor ranges restrict exposed-lead bullets, so check before an indoor session. If recoil matters more than margin, Black Hills Cowboy CNL still makes 126 with less kick, and Remington UMC LRN at 119 is softer again for pure paper work. If you want jacketed +P practice, Speer Lawman +P 158-grain TMJ is 60 fps faster with about 12 percent more recoil energy and needs a +P-rated revolver.
