I am glad not to be born and raised in Pennsylvania, having to deal with the flintlock regulations they have there. Here in Michigan, I see a flintlock in the woods once every 7-8 years...... that's it. They are the rarest of rifles here.
I have never owned a Flintlock, or a package of pellets. Sold all my sidelocks except one. These days, I am so-married to inlines, plastic sabots, removeable breechplugs and Blackhorn 209 sub powder.
