I picked up a used Model 16 Lefty Stainless Weather Warrior for my son in .243 and I have to say it is a good shooter. It has the aluminum Accustock and it shoots most any ammo at .75 MOA. I spent countless days at the range trying to get a good load for my Sako .243 and we just went with that load for his Savage .243 which shoots great. Now I plan to use a 280AI for myself and I'd like to upgrade my son to a larger bullet and it was advised to me that I could rebarrel his Savage with a 7mm-08 or .308. We are non-lead out here and with the twist rate, the .243 is limited to about 85gr mono.

Are there any good sources for used stainless model 16 barrels in 7mm-08 or 308 (or even 260 Rem)? Probably need a barrel nut and recoil lug too- the stock barrel nut is smooth so guessing it might get marred upon removal.
