Baer custom rifles has a few new rounds out, one of which is a necked down 408 chey-tac. Anybody know anything about these rounds or heard anything about them. Doing some research on maybe building a new rifle with a custom action. Not sure I want to invest in a rifle if I have to rebarrel it every 650 rounds. 408 has excellent ballistics in and of itself, but bullet choices are few. The 338 version sounds like a great idea. Any information would be greatly appreciated.
