One of my spring projects is to work up some loads for a 45 Colt. Specifically, I have a 20" 460 S&W Magnum barrel for my TC Encore and I am after something a little less punishing (Something like a 2600 fps 240 gr bullet out of a 5 lb rifle gives me pause). One thing about this load is that there will be a long jump to the rifling (Something like 0.5 Inches). Any one have an idea of how this jump will effect accuracy? Or does it really matter with this rifle? Data point: The last time I shot this gun with 460's I was getting about 1 inch at 50 yards.
