I am looking for a good muzzleloader. A good local gunshop has a used stainless omega, gray thumbhole stock, with 4x scope. They are asking $379. I this a good price? Look like I can get a new one for around $500. The said if I wasn't happy with the performance they would give me a store credit. I have several muzzleloader in the $150- $250 price range and would like somthing nicer. Not sure I want to spend the money for an encore. Any advice apreciated
