I would have to ask, how much does it weigh and is it hammerless. Bore rifles can be further broken down to include smooth bore guns. Generally these guns have hammers, shoot between 4 to 7 drams of black and weigh between 9 and 13 lbs.and intended for ball or conical only. Ball and shot guns are more like modern day shotguns capable of shooting both shot and slug, weighing 7.5 to 8.5 lbs, usually hammerless,not always.
