Encore 50 cal. stainless MZ tube, shoots 250gr. shockwave well & 250XTP with 2 pyrodex pellets or 80-90 gr. of TTT7. Inside of bore is like new, has some very small corrosion markings on outside of barrel under the sides of frame, from moisture setting there on a hunt. I tried to get that in the pictures, but they are very small. $200.00 shipped.
