Any reliable scope should work just fine for either method. You'll need to actually shoot at the ranges you want to cover to be certain anyway.
I agree. I've never had any problems with the Leupolds I've used on the various muzzle loaders or magnum center fire rifles I've owned. When I had a Savage 110ML, I shot some brutally recoiling loads. Nikon, Leupold, Burris, etc. should serve you just fine.
