That's real interesting. My uncle bought an encore last fall as a muzzleloader and then also got a centerfire barrel for it. Hasn't shot it much, but he DID have a few misfires with the centerfire barrel. We were figuring it might be a bad lot of ammo he was shooting, but now I can suspect something different. A gun with that price tag, and that claims the ability to swap barrels with little effort should NOT be misfiring with any of the barrels in my opinion. I don't know, for all the accolades this gun seems to get it sure does seem to have a good many imperfections. I can't say that I have had similar sets of problems with the other guns from well known manufacturers. A good many cost a good deal less also.
