Funny you should ask, I have been eyeballing that one myself these last few days. If it shoots as well as my MVTCo Long Land Bess then I would be happy with it. That Bess has made me reevaluate my opinions about musket accuracy, it was a lot better than I was expecting from a gun made in India. No offence to India but I have seen a lot of total crap guns come out of there. I have one of their ships carbines expected on Monday, I will see how that goes before I consider the Potzdam, one nice gun could be a fluke, two would be the start of a pattern. I have read some comments about the Indian guns in other posts here, bad triggers, and other complaints, I had no problems with the Bess in this regard, but then I have a lifetime of shooting post 1865 military surplus infantry rifles from all around the world, I am well used to heavy triggers. The Bess ran around 6 pounds by my own feel as I don't have a gauge to test it proper. I have been looking over their pistols as well, I like that 1756 sea service, and the 1733 French, whatever their quality they can't be worse than some of the 1970's Japanese made "Tower" pistols I have seen, and owned.
Sorry, I should have said smoothbore accuracy, my Pedersoli 1863 rifle/musket has always been a good shooter.
