WNY_Whitetailer, Jack Weigand my recommend three or four ring sets for the S&W 460 and 500 shooting heavy loads, but it is not needed. I have well over 2000 rounds through my 460 Mag shooting heavy loaded 300 and 325 gr. bullets and the scope has not moved at all.
Why wouldn't Jack Weigand recommend 3 of 4 sets of ring, he would make a lot more money on the sale of his rings. On yea, my 500 Mag only has two rings also, and well over 3500 rounds down the tube without the scope moving. Sometimes I think people do it more for the look than for practical reasons. Yes Weigand makes very good rings also, but 3 or 4 sets of rings??
