The Signature line's 250-grain TMC is a full-weight .45 Colt range load with its lead fully encased in a total metal case, so none is exposed. It leaves the muzzle at 842 fps for a power factor of 211, 28 percent over the 165 USPSA major floor and far clear of the 125 minor floor. From a 25-yard zero it sits 2.7 inches low at 50 yards and 18.4 inches low at 100. Pressure is standard.

Its closest peer is Fiocchi Training Dynamics 225-grain CMJ, the other ball load here with its lead covered. The Signature's bullet is 25 grains heavier and 92 fps faster, which lifts its power factor 42 points above the Fiocchi's 169, a margin a short barrel is unlikely to erase. The trade is recoil: the Signature produces about 48 percent more recoil energy than the Fiocchi in the same revolver. Neither bullet expands, and both are built for paper and steel at ranges that restrict exposed lead.

Buy it for major-power practice and steel work at ranges that restrict exposed lead, or for a shooter who wants a full-weight bullet at standard pressure without buying a hunting load. Shooters who want lighter recoil for long sessions should take the Fiocchi. If you want a hunting load and your revolver is a large-frame Ruger or similar rated for +P, Underwood +P 250-grain XTP JHP runs 1,400 fps with about 136 percent more recoil energy in the same revolver. The maker restricts that load to guns rated for it, so check your revolver's rating first.
