The chambers on the 7.62 NATO conversions of the 1895 ans 1912 Mausers are done in an unsafe way, in my opinion. A sleeve is soldered into place in the 7mm chamber and the barrel is rebored to .308", then the chamber is rechambered to 7.62 NATO. The only problem is, There is usually a gap between the front of the sleeve and the rear of the throat. Not a good thing to say the least. Also the front of the sleeve is rifled, then the GAP then the rifled barrel. A Chilean 1895 Mauser was designed to handle 45,000 PSI ammunition. The 7.62 NATO generates a lot more pressure than tha and the .308 Win is even higher. THe 1912 is a 98 Mauser and able to handle the 7.62/,308 pressures.

From what I have read about the "308" 1895 Chile Mausers, I agree with you. First, NO commercial 308 pressure (62,000 psi) ammo. And don't expect to fire 1000s of 7.62 Nato (60,000 psi) ammo through these Mausers. Yes, the original design was for 7mm (7x57) which runs 45,000 to 47,000 psi. I also have read that the 308 Chile Mausers were re-heat treated to make them a little stronger, but still not up to "308" standards.

When I finally get a bolt for mine............ I will let you guys know how 7.62 Nato ammo shoots. Plus, I can always reload down the ammo......
