While I have no experience with the "Mississippi" Rifle, years ago I had one of their Tennessee Mountain Rifles in 50 cal. It was a flintlock with a full length cherry stock. Beautiful rifle, and shot balls very well. I never tried shooting conicals, figured that would be blasphemous out of a flintlock. Seemed like heavy charges of Fg shot the best, sure wish I'd have kept that rifle. Oh well. Never put a price on gun you do not want to sell. Period.
