I'm looking for some opions/thoughts on using the following load for elk hunting this next season. 500S&W using Barnes XPB 325 grain, 2000 ft/sec, 2800 energy. I know this may seem a little extreme, but rather be overkill than underkill. Anyone have any experience with Barnes XPB bullets? This load seems to provide the highest energy levels for the 500 S&W.
