What scope do you guys prefer on your muzzleloaders?

My preferrence would be for a simple 3-9 x 40 Leupold Rifleman. I assume it would stand up to the recoil just fine. I shoot Leupolds on my .300's and 30-06's regularly and have never had a problem from V-x1 and up.

I just think that a simple scope would work pretty well since the ranges are fairly close, say 250yds at most.
