I saw the GunTalk episode discussing the Doubletap 450 Short Magnum Cartridge that works in full size 1911s and with the 185 grain getting 1,350+ fps delivering 735 ft lbs i decided i just had to have some for SD rounds. While i was at it I went ahead and got some 230 grain at 1200fps with 650ft lbs. I'm going to crony some up myself to see how they really are.
Well, I now realize that I need a heavy duty recoil spring. What weight of spring would serve best for a round like this?
I think its just crazy that they cut down a 308 cartridge and are still using magnum rifle primers in a 45 round.
