for me I load light .308 loads to begin with on this rifle.
if you do shoot 308 or nato loads, keep an eye out for signs on the brass and the gun that are precursors to failure.
I would bet to say that you could get by shooting 308 commercial loads for a long time as long as you pay attention to the gun and ammo. if the bolt is hard to lift or the brass shows stretching, etc... then you over did it. militaries will always load way past max to proof test actions to see exactly that their limits are. if the nato loads were close to the max for these guns then they would have never converted them.
