hello everyone, new guy here ! I have found that any Kieth SWC at 950 mv, or above, in a 44 Mag. will work fine at handgun hunting ranges, as long as it is accurate and you can shoot it well. Hi velocity is not needed on deer, as i have killed 5 whitetail deer with a 45 ACP (1911) (5in. govt. mod.) none of these deer went over 50 ft. after being shot. Greg Bayes
