I own a Mossberg 500 that has a 50 cal. conversion barrel. I have been using Buffalo bullets and want to know if anyone has used sabots and what's your feelings on them. Also question on Pyrodex pellets, how long can they keep? It seems that every once in a while I get what seems like a misfire even though the primer fires it sounds more like a dud than the normal blast.
I'm a rookie here so bear with me [&:]
