Georgia Arms has finally made the Big Medicine for the .45 Colt: a 260 grain JHP traveling at 1200 fps. This load should be safe for any modern .45 Colt, but still plenty of UMPH! for close deer and black bear. If penetration is adequate, it should also be a fine hog gun.
This load is a welcome addition to the scene, because .45 Colt tends to either be loaded very lightly, so as to be safe for old guns- or loaded very heavily, for super-strong firearms like Rugers that can easily handle .44 Magnum pressures. The GA Arms load gives a good middle ground for loads that won't kill your wrists or wallet, but still give a good bit more potential. I'd love to see a 300 grain Colt hard cast at about 900 fps from a 4" barrel next.
