I've read that the millitary M40 sniper rifles begin their lives as Remington 700 model rifles and that the 7.62mm NATO rounds they fire are equivalent in caliber to a .308 Winchester. If this is the case, could a Remington 700 chambered for .308 fire the 7.62mm NATO rounds? If so, would this cause any sort of exessive wear or damage to the gun?
Is the opposite true? Can the M40 fire regular cheap .308 winchester shells?
I don't know about the M40, but the same is true for the M16 with the 5.56mm NATO caliber versus the .223. I'd ask your question on www.ar15.com, they thend to be pretty good with tactical weapons.

The 7.62X51mm NATO round used by the U.S. for sniper operations is essentially the same as the U.S. National Match round. There is no reason why you could not fire this ammo in any commercial rifle marked as being chambered for the .308 Winchester cartridge - and vice-versa! They are basically the same in all critical dimensions.

Been firing 7.62 mm military ammunition in my .308 guns for over forty years. No problems at all. Still have my first .308 chambered rifle. Is is a rebored and rechambered Mauser 95 that was originally in 7mm caliber. This gun still shoots 1.25 inch, 100 yard groups with iron sights using M118 Match ammunition, Lot LC 20-1.
