I do not recall any flame or smoke coming from the bottom of the one Taylor made, either. There was some wafting from the top of the screw, or it could have been from the pan only. Pouring in the powder, winding the scrw up, then wiping the excess that is carried up by the screw, sideways into the pan for priming, sure speeds up that process. It is a fast firing rifle, that's for sure.
