I once attempted to purchase that exact rifle. I ordered the PA Pellet Flintlock 50 caliber. It has a 1-48 twist. And they shoot roundball and sabots very well from people who own them have told me. So I ordered one, the online store said it was in stock, then they emailed and said the one I ordered had been sold and were going to send me a camouflage model. I told them no thanks.. I like my rock locks natural looking.
The reason I was going to purchase one was because of the recommendations of two owners. Also, this is one that on the newer models I believe you can take the breech plug out of them for easier cleaning. But don't quote me on that. Also I have two Tradition Flintlocks. Both of them have excellent, fast locks. They are very good shooters. I instead purchased the Traditions Woodsman (better wood) in 50 caliber and it is a great flintlock rifle.
I was in the same boat as you.. I had an itch and could not see a rifle that scratched it. That was why I did what I did.. This last purchase should scratch me nice and deep and keep that itch at bay.
