I have the #8245 .50cal 250Gr. superglide shockwaves and they work great in my Traditions Muzzleloader.
No problems at all, nice snug fit and they seat very well.
Have you been using them right along or are these new to your muzzleloader?
Democracy is two wolves and a lamb voting on what to have for lunch.
Liberty is a well-armed lamb contesting the outcome of the vote.
