I can't imagine shooting a 6 1/2 pound .500 BPE. Granted teh bullets are light for calibre, but even my 10 pound Sharps kicked pretty hard. It was bad enough I got rid of all my 3 1/4" cased Sharps. Too hard to work up good BP loads in and too much recoil for shooting a lot.
; That's a very special rifle, though.
