I own a couple of what I would consider low quality muzzleloaders. There are two of them that are hard to get anything to shoot well out of them. Yet a couple of them, while their stock to barrel fit is poor, they are very good shooters. But I would not call them quality.

Also I never take cost into the overall question. I have some rather cheap rifles that I feel are very high quality, and they shoot like it. But like Lee said... if you really look at them, would they last a life time and be something you'd pass down?
