I have a smith 629 6" I will be hunting with this deer season. My gun shoots a cast 240gr swc with 10gr of unique under 1.5" at 50 yards. Would this be a sufficient load for hunting whitetail out to 50 yards. Or would I be better off to shoot a barnes 225gr XPB over 18gr of 2400 that groups 3" at 50yards. I know the 44mag is capable of taking whitetail but I am worried about shooting the XPB and the expansion at the slower velocity.
