Well there is one thing; that is the phoniest claim ever made, when they had to do something to compete with the Triumph which may well be the most accurate out of the box muzzleloader.
A side from that in any model of any brand there is always the chance of a lemon it can happened.
To be honest that sounds more like a bad scope than a bad gun. The only defects that I can think of that would not be obvious would be a bent or laminated barrel. A loose action might but should be easy to spot. Come to think about it they did have some laminated barrels at one time but that was a long time a go. There service department is supposed to have become contactable you might try them.
