I have a Ruger Super Redhawk 7-1/2" 44mag. and my Hunting Buddy has the same one you have. We both Have Millet Red Dot scope with 3moa dots on ours. Works good and have not had a problem with them. Alot faster with the red dot then a powered scope. Been accurate for us in hunting situations. Millet Red Dot scopes has held up to stiff 320 WLNGC hard cast handloads at 1331fps.
