I have a .30-06 with mcmillan stock etc. What would it take to change it to a .338 lapua? I have tried to find out if they take the same length action but couldn't. I know the bolt face would be different.
i'm assumeing its a rem 700?
you would need to have the bolt face opened up, and have a new extractor installed, and get a wyatt's extended mag box installed, or get the DBM of your choice...
i'm not sure what the going rate for opening up the bolt face is, you'd have to have a new extractor installed too, if I was you i'd order a new bolt from PTG that is alraedy set up for the lapua, take your action to a smith and have him gauge it so you can get a bolt that is closer to the diameter of your action, tighter tolerances = tighter groups, if you keep the factory bolt, i'd have the rear of it sleeved
Yea, in my experiances once you start going down the lines of radical change you're better off keeping what you've got or selling it and just starting fresh.
