Gunsmithing 338 Lapua receiver specs

Re: 338 Lapua receiver specs

the 30-06 and the .300 win mag have the same feed rails you need to go off of a ultra mag action to get the .338 lapua to feed. my suggestion would be to use a ultra mag donor action and save some time and money

A 3006 bolt will open to accept the .590 case head. Your extractor will need replacement too.

As mentioned this isn't advised. Ten years ago everyone was doing this. Myself included. I've made AI 338LM's before on 700's. Don't anymore though.

I agree with others that an alternative action is prolly the better choice.

I know the bolt face is different. I was planning on using a CEG bolt from midway. Maybe I'm using the wrong terminoligy. The area where the magazine fits into the bottom of the receiver is different on the 30-06 compaired to the 300win. Is it different for the 300 RUM or 338 lapua?
If everyone says its unsafe why does remington make them? I don't understand unless there is something way different between the receivers on there 338's compaired to the 300 or 30-06.
