I see at a recent BP. shoot that shooters were shooting .680 DIA. RB'S in paper cartridges in a .730,.735 DIA. bored BROWN BESS MUSKETS. why was this being done? why not shoot the size ball corresponding to the bore DIA ?. I shoot a .725/.730 DIA. RB patched with a .010 pillow ticking lubed patch in my BROWN BESS REPRODUCTION. wouldn't the reduced DIA. RB. go WILLEY NILLEY when it leaves the bore?
