Gotta ask this question because i genuinely just don't know, but has anyone ever seen modern muzzleloader bullets (power belts, etc.) fired from traditional muzzleloaders. i have random packs of 50 cal powerbelts laying in my gun cabinet but no in line muzzleloader. but i do have a 50 cal Thompson center Hawken that i would like to try them with ( if that's feasible) I just fire lead round balls out of it. i know that i can't fire modern smokeless powder or pellets but maybe if i stuck with black powder it may work? i feel like only a pilgrim would ask this question
