This is probably a worn out question but I keep seeing remarks about being careful not to shoot 308 surplus ammo in a 1916 or converted 1893 Mauser. The reason being that the ammo may be loaded hotter for machine guns. Has anyone actually seen evidence of metal fatique or high pressure signs that would warrant these assumptions? I know the small ring receivers are not as strong as the large ring but still a Mauser action is among the strongest and best. Also, we are talking about a .308 Winchester round not a 375 or .458mag round that the large rings can handle. If true then what about name brand off the shelf 308 ammo such as Remington, Federal, etc..?
