I chatted with Jon over at Savage-barrels and he's under the opinion these use the same bolt face, so I'm checking into that end of tomorrow. These chassis are the exact same chassis no matter the caliber, in fact the barrels are the same (just a different chamber) and the brake is different having a slightly larger hole for the .038" bigger bullet. This isn't as difficult as a lot of people tend to make it, and as far as getting a smith locally with a FFL to buy it for me, NO problem. I'm just trying to get the source... I'll take care of the details as the come along. As far as package deal accuracy, if I can get a .338 chambered barrel as good as this factory one, I'll be more than happy. This .300 win mag shoots under a 3" group at 550 yards currently and at a 100 it's just under .5 MOA capable. This rifle currently shoots better than I can, so things turn out equally in the future with the barrel swap, I'll be a real happy camper.
Thanks everyone again for your replies and support.
