I have a traditions 50 cal. deerhunter sidelock that likes to hang-fire when I load it with conical bullets, It seldom does with rb's or those plastic things with pistol bullets. I understand this is not a top quality gun but why would different bullets make any difference. I usually use cci magnum caps but have tried other brands,tried pyrodex RS,P and 2F goex with similar results,have also tried different nipples, always tap the butt and smack the side during loading. Don't have issues with my other guns. I suspect it may have something to do with the rb holding more pressure upon the charge while the conical is "loose". Any thoughts ??
