It's been years since I've shot any of those heavy bullets out of a acp. I used to have an old lyman mold 454613? & shot them for a couple of years. I found that they didn't do anything major to improve my times & just beat on the 1911 more than it ever deserved.

I just use a 200gr bullet anymore for everything in the 45acp. It seems like an excellent speed/weight ratio that's easy to grip it & rip it.
