Re: 338RUM & LM base and ring setups and problems
For that big of a cartridge and that light of a gun, and no brake to boot those weaver rings are NOT up to the task. The lowest quality rings I would even think about considering would be the Burris extreme tactical rings. But ideally warne steel rings or nightforce, badger, etc.
