I have heard that as well.
My personal opinion is that they should. We are fortunate enough to have a state that maintains a muzzleloading season as it should be....flintlock, open sights...and tradtionally was roundball for many years.

A roundball is plenty accurate and deadly for pennsylvania game. Let's keep the season historically correct and tradtional. Inlines are fine for states that don't allow high powered rifles......but keep them out of our muzzleloading season. Going back to roundball only will help maintain a great tradition.
