Ok so I would consider myself fairly new to long range marksmanship, but not a complete novice. I have an extremely nice .260 built on a trued 700 SA and Benchmark barrel. Shoots <.5 MOA if I do my part. I have found a custom rifle maker who trues 700 actions and builds some extremely fine rifles and I want to move up in caliber; however, can a 700 MA be worked to shoot a 338 lapua, and if it can, does it hold up, or do I need to go with the perverbial Stiller, Badger, Surgeon, and etc.? Thanks.
