Copies this from a website I just found:
Smith & Wesson recommends that only quality steel bases and rings be used, and highly touts those manufactured by Warne. In fact, both can be purchased directly from the company. When mounting the base and rings, Loc-Tite is absolutely necessary for prevention of screws backing out under the .460 S&W Mag.'s stout recoil.
When choosing an optic, select only quality scopes designed for, and tested on, big-bore handguns. Bargain-priced scopes will not hold up to the stress imposed by this cartridge! The top choices are Leupold's FXII (fixed-power) and VXIII (variable-power) handgun scopes, as well as those in Bushnell's Elite 3200 line. If possible, opt for a matte finish, as those with a gloss finish tend to move more readily from recoil. A third ring can help prevent this, and is recommended. While I've yet to try them, a red-dot optic should make for a nice addition, given sufficient quality.
I've heard Ultra-Dot's are nice for high recoil handguns, but I can't say for sure. Could be a cheapo. I know Ronnie Barrett puts Bushnell 3200's on his .50BMG's from his factory (if wanted). His shop is about 30 minutes from me but I still haven't been inside it....
