I have a 7 1/2" Ruger Super Redhawlk in 454 .
I have 2 sets of rings ,1 set has a Bushenell 2x6x32 scope ( several thousand full power rnds and several thou target loads ) that works perfictly.
Second set of rings has a Millit 30mm red dot ,I have run more ammo with this than the scope. I use this for deer hunting . 4 shots 5 deer ( don't ask)
The only problems I had with either is the scope slid in the rings till I locktighted the rings to the scope ( with 360 gr hard cast bullets at 1400 fps)
