Professor - I have the same rifle I picked up about 6 months ago and went through the same questions the end result is I load 308 ammo to the below specs functions fine and the pressure should be around 38,000 cup give or take:
I use lake city brass so the below load is -2 grains to account for case thickness.
147 grain pulled m80 bullets - purchased from
Longdayjake at rocky mountain reloading
39 grains of IMR 4064 (if you are nt using military brass use 41 grains)
This load shoots great out of mine m1916 to about 1.5 - 2 moa. Let me know if you need more info.
