I have a question to all you goroo's I hunt muzzleloaders and was recently givin a keg of shot gun powder . and was thinking that back in the day they converted muzzleloaders to smokeless powder but now they say not to use smokeless powder in your muzzleloader my question is WHY if you get the equivalent measure it be fine. however I don't want to f@%#@ up so I thought I would pick other brains. if the measure of energy is = it should work RIGHT???
