Was looking at Double Taps site to order some 10mm and 9mm ammo and noticed they have a 45 Acp load that made my heart skip a beat. It's a 255 grn Keith style bullet loaded to 875 fps from a 5 inch barrel.
I'm going to order a box, and see how they do in my Colt. Then I'll see if I can duplicate it at the bench. This load may give the 45acp status as another great dual purpose cartridge for woods protection carry. I think the energy figure was in the low 400s, but, energy is not an indicator of what the potential for this load has.
I assume it's not gas checked, because they do not recommend it for Glock pistol style barrels.
