My 54 has a 42 inch Colerain barrel, the range was right at 20 yards. I used my decoy for range stakes, and he was beatin' the hell out of my Jake. A lot of load testing was done, that one was 80 grs FFFG, an over powder nitro wad, a fiber was dipped in hot patch lube, my shot package is two thicknesses of butcher paper, both ends tied with string, with the front end ripped off, and a card over shot wad. I prime from the horn with FFFG. Not one BB was below the crop. I was pretty happy about that.
