My experience with Pedersoli's thus far is with the Dopietta shotguns, coming from good quality SxS internal hammer cartridge guns. The Pedersoli's handle quite well, and the triggers are good shotgun triggers. They are a bit heavy, 20 gauge is handier.
Concerning fit and finish. Inletting is adequate at best, but noticeably better than Thompson. The semi beavertail "forend" is actually quite elegant, and the case hardening holds up surprisingly well.
The locks feature a flat main spring and searspring. This is pretty PC (where you can't see it) but it doesn't really make them shoot better.
Given that this is a percussion rifle forum, I don't get the "long rifle" brouhaha. Those rifles pretty well all began life as flintlocks. Pedersoli's Plains Rifles are pretty good reproductions.
There certainly was a major shift in exchange rate between the Euro and the Dollar around 2006. Inventory overhang (or lack thereof) would influence cost for some time. There aren't a lot of Pedersoli rifles that cost more than a Jim Chambers rifle kit--which is semi-custom, but completely unfinished.
Hopefully, we all shoot guns we love.
