Was not trying to step on anybody's toe's, please accept my appologies that was not my entension, Thank you Rickey.Careful, there Rickey. Dont get your pants into a wad. i imagine i've been shooting muzzleloaders as long as you have. Yes, i do know not to shoot smokeless in a M/L. The man asked a very simple question and i answered it.
