Just curious as to if it is a good idea or not to use a long action 700 action for a 338 lapua. I have read things about wall thickness, etc. but would a magnum action be different from say a 7mm mag or 300 win mag? I know they make the Remington 700 MLR in 338 lapua but I am not sure if they use a beefier action from the start or just a different bolt/bolt face and extractor? I have plenty of long actions laying around is why I ask. It would save me from spending a lot on a custom action but I don't wanna do it if it's going to mean cutting corners. Thanks guys.
