I like Leupold. Great scopes, a little expensive.
I do have a Burris Fullfield 2 on my Muzzleloader though. And it seems to be a great scope for a mid price range.
My first was a Simmons. Now that scope, I have to say, never failed me. Even after a nice drop down the mountain on to a rock..(sling failed) Dented the windage cap pretty good. Still dead on after that. It was just darn dark to look through compared to better optics.
