For more years than I care to count I've used the Weaer rings and bases. I still have a couple mounts using the old style rings that clamped only on one side of the scope and they've never failed. Even used them on the .375 H&H Mauser and a Winchester M70 .375 H&H. I still use the Weaver bases and the Weaver 4x4 rings and have them on at least fours that I can think of offhand. Those 4x4 rings are really light weight but so far have held up fine on a 30-06, a .280 Rem. a .300 Win. Mag. and the .35 Whelen. Looks to me like they just plain work.
