Oh, I believe it could be under heat treated and soft which could cause the bolt lugs to set back in the receiver and eventually develop excessive headspace but how do you double load an '06 (or an '03 as it was originally)? 94 grains of 4320? 106 grains of 4350? Try it and see how far you get. Or just a case full of Bullseye? That would do it with any rifle. There's a nice photo online of a receiver with a crack about halfway from back to front. Oh heck, you only need half a receiver. Let her rip! Hey, it's been shot for over 100 years, it's good for a lot more. Personally, I'm very attached to my fingers and my eyes. Have at it if you want.
