Need More Help/Info Please, I have the supposed re-bored/chamber insert ???? 29 inch long barrel, like new condition with great bluing. I cant see the " insert ". Could this actually be a NEW barrel ??? Also, can I safely shoot 308, I dont understand why it is so much more pressure than nato 7.62X51, they look to be the SAME in size cartridge ????, Thanks Much Guys

OK, here are a couple of other things to look for. Is the barrel an original German made barrel? If it is, it will have a serial number with an acceptance mark above it. The mark is a circle within a circle with 4 equal spaced marks between the 2 circles. Most of the serial numbers do not match the receivers. The back of the receiver will be stamped "7.62 N" with the N under the number. The receiver and the barrel were blued whereas the original receivers were in the white. I can see the insert in mine by looking at the extractor slot cut in the receiver, the insert is not the same color as the receiver and a faint line is visible. If yours does not have these characteristics, someone may have installed a new barrel not of Chilean origin, however I do not know of any other 29" military barrels that were original 7.62. It would have to be an after market barrel. To get a 7.62 chamber in a 7x57 Mauser barrel, you just about have to use an insert because the 7,62 case is so much shorter than the 7x57.
You can shoot the commercial loads in the re-chambered rifles and not expect an immediate problem, but there is probably going to be erosion with time and a higher pressure load will accelerate this. There is a web sight by "Dutchman" ( goggle "Chilean chamber insert" and it comes up first) that shows the erosion of the soldered joint with time and explains the difference between nato and commercial ammo.

To the best of my knowledge, all the converted Chilean 1912 long rifles (29") with their original barrels use the insert. There is a Chilean 1912/61 short rifle that uses surplus US Model 1903 barrels 24" in length chambered from the start for 7.62 NATO.
Thanks for the GREAT info, I do have the original German barrel, Im assumng 7mm rebored/rifled to 7.62 nato, the Duthman info seems to be about the 1895 models, mine is 1912 model 98, So I guess I can shoot BOTH 7.62 and 308 ???

I'm sorry, but everything said about the insert for the 95 applies to your 98. It has an insert. As I said, you can shoot the commercial loads but expect the errosion to occur quicker. It wasn't a good idea the Chileans had but it probably was a stop-gap measure not intended to last forever and was cheaper than new barrels. I don't know what will happen when the errosion gets bad but I am going to find out. I shoot mine often in Military Bench Rest matches at our local club but as I said in the first thread, I use lighter loads.

THE 1912 long rifle conversions are hard to find.The 1895 carbine conversions are also hard to find.They are marked 7.62 or 7.62N-these are 308 conversions-the 1912 & 1912/61 are the better conversions than the 95 IMHO.There is also a spacer in the triggerguard to make up for the shorter 7.62N or 308 cartrige from the orginal 7mm mauser.I have seen some of the 12/61 conversions missing the spacer/ramp in the TG.As far as 308 vs 7.62 nato it will shoot both-I dont want get into the arguement on the differences between the 2 designations,I shoot either one in my FR-8,12/61 and Israeli Mauser.
