We are talking about a muzzleloader, right? I assume you will not be taking any shots over 200 yards for certain, and likely not much beyond 150? I would truly not look for a scope with any more power than 3x9, and lower yet would likely be better overall. I guess personal preferance and maybe poor eyesight can lead us to higher power scopes. You can easily buy a Bushnell 3200 Elite at just about any power for under 3 bills. Good luck.
