He emailed me back. Said that single shot short action 700 would be my best option with the RemAge barrel. As far as pinning the lug, since this will be a dedicated ML I really don't see the advantage to pinning one since I won't be spinning the barrel off and on with replacements. I am assuming (I know, stupid to assume) that if I go that route, it will be pretty much the same as spinning a barrel on to a Savage correct? Just set it with a GO gauge and torque to 40 and give myself around .003 leway?
