I'm trying to develope a defence load for a Taurus 450 , a K-frame,45lc, 5 shot, 2" barrel, snubbie. The frame seems pretty stout, with a gripframe similar to a gp100. Because of the short barrel it will be hard to get any good velocity with a 230-260grn bullet. I'd like to get something like a 230grn hp going around 800fps None of the loading manuals cover a short barrel though. Any suggestions? I forgot its a solid 29oz. Stainless model.
