Very Interessting, 450 - I've wondered why the reluctance to allow jacketed here with BP, and some events only allow outside hammers. I am referring to North American shooting, of course.
: I wouldn't have thought to try jacketed with BP, until my Bro did it with the .45 3-1/4" chambered Sharps.
: It was amazingly accurate. No lube of any kind, just a stack of wads to take up the 'extra' space left by the 110gr. gr. load.
