Remington's UMC 125-grain is a jacketed soft point, a lead-tipped jacketed bullet meant to expand more slowly than a hollow point. Remington lists 1,450 fps and 584 ft-lbs at the muzzle for this .357 Magnum load, a power factor of 181 that clears the 165 major floor by 16 points. From a 25-yard zero it is 0.7 inch low at 50 yards, where it is computed to still carry 427 ft-lbs, and 6.6 inches low at 100 with 330 ft-lbs left. The case is plain brass. The recoil estimate lands in the middle of the comparison set.

Against the other 125s this load sits in the middle. Winchester PDX1 Defender 125 is 125 fps and 97 ft-lbs behind it. Hornady American Gunner 125 XTP and Hornady Critical Defense 125 FTX list 50 fps more, though Hornady rates its loads under different test conditions than Remington, so that gap is a published figure and the brands are closer than the sheet suggests. Where the Hornady pair does hold an edge is downrange: American Gunner is computed at 1,165 fps and 377 ft-lbs at 100 yards against 1,090 fps and 330 ft-lbs here, with 0.8 inch less drop, and Critical Defense is within 2 fps of that. The 158-grain soft points bracket it. PMC Bronze 158 lists 1,471 fps and 759 ft-lbs at about 64 percent more recoil energy in the same revolver. Federal American Eagle 158 lists 1,240 fps and 539 ft-lbs, so it is both slower and lower on energy than this 125.

Buy it as a full-power 125-grain load for a mid-size or larger revolver, for a shooter who wants a soft point rather than a hollow point and a power factor with room to spare over major. If the recoil is more than you want, Winchester PDX1 Defender 125 gives up 97 ft-lbs but still makes major at 166. If you want a heavier soft point, Federal Fusion 158-grain lists 1,240 fps and 539 ft-lbs, 45 ft-lbs less than this load, at about 22 percent more recoil energy in the same revolver; the extra weight buys mass, not energy.
