Awhile back I was studying the 45 Super and decided I wanted to give it a go in my Kimber 1911. I purchased a 26# recoil spring, and left it on the shelf for about two years before I finally got around to testing ammo.
Over the last couple of weeks, I have worked up a good load for my .45. I have a Lee 255 grain flat nose bullet, which I loaded over 6.8 grains of Longshot; this being the max charge for a standard 230 grain .45. I also loaded some 230 grain lead bullets over charges from 6.8-7.2 grains of Longshot, working my way towards 45 super load data.
The result: a 255 grain WFN bullet coming out of a 5" 1911 at 925FPS. The 230 grain bullets did about the same velocity with the 7.2 grain charge, which I attribute to a reduced case capacity with the heavy bullets.
Empty cases were ejected at the same location as my standard ammo. Groups were roughly 2" at 15 yards offhand.
These loads are somewhere between +P and .45 Super. I am ready to give them a try on a critter.
