I have the Optima pro and have shot it for 3 years. I don't really understand how you can haveproblems with a gun that has such a simple design, there really isn't much that can go wrong with it. If your looking for a straight muzzleloader it's a great gun for the money. Mine shoots just as good as my buddies Encore at 1/3 of the price. I have a Nikon Pro series on mine.
