Not sure of your budget. If your ML season is a ways off, then I suggest that you put aside th $100 now and save up these next several months and buy a scope in the $250 range rather than a scope in the $100 range. losts better glass in this price range.

Shots with a ML are usually going to be makeable out to about 200 yards max, so I see no need pay extra for the 8X to 12X powered variables. Something like 1.5 - 6 x 40 mm variable should be excellent.

Leupold, Vortex, Nikon, Burris, Pentax, and Bushnell all make good scopes in this price range. Everyone has their favorites ... in the $250 range I am partial to the Leupold line. Up to now I have not been a fan of Nikon scopes, but I recently put one on my Cross Bow. And frankly I am impressed. This is a BDC type reticule and though I am still getting used to the "business" of the reticule, it sure came in handy during this past bow season. And was bright and clear right up to the end of the day. I think that Nikon also makes a BDC model specifically designed for muzzle loaders.
