Mueller scopes really look great, here lots of good things about them. BUT, a friend just mounted one on his A&H .50 cal and when i looked through it, it was like looking through a tunnel. The image did not fill up the eye piece. If I were you, I would check them out at a retailers and see for yourself. I don't know if all the models are like this or just the particular model he has (4-16x50) which is a lot of scope for a muzzleloader. But he intends on trying to win a local shoot this fall and thinks the scope will help. :lol:
