Re: Weathrby Actions
You could, but I would not. I don't think there is anything wrong with the action, and your problem with it's accuracy may not be either.
I am building a 30/338 Lapua Imp for my wife and will be building a 338 Lapua Imp this fall for myself. I am using M-700 doner actions that have been trued for the projects and custom barrels with custom stocks pillar bedded. Formuala for success, as I see it.
Simple, straight, and square.
Some like Weatherby actions, I am just not one though.
