Knowing Nothing about 1911 or 45 ACP

I have used 451 and 452 in various 45 ACP 1911's and others over 40+ years. I finally settled on 452 as the best a long tie ago. Really depends on the barrel bore. If the 451's shoot good enough for you, then stick with it, unless you want to buy a 452 and try it. As for the brass, you might try using a large tarp.
