Well, I said I would give my Buffalo Bore Keith SWC HP's a try on a Texas whitetail so I'll be giving them a shot this weekend. These are the standard pressure dead soft lead versions with a velocity advertised at 970 fps from a 4" revolver. I've use the commercial version (old FBI load) before and it did about as well as a .357 Mag would do through both lungs. My gun will be a 4" S&W Model 10-7 (tapered barrel). I'll give an update when I get back from the ranch. Good Hunting to All!!!
