Looking to build a no holds barred .338 Lapua Improved and trying to decide on an action. This will be a single shot only rifle since COAL will exceed CIP magazine length, and I want the rigidity of a single shot receiver. Right now the Surgeon XL single shot is at the top of my list, but I want to know what else I should be considering. If you were selecting the best action available for a Lapua based cartridge, what would you choose?
