The Steyr Model 1912 is a darn good and very strong rifle well suited to about anything you can fit in it.įor current 7.62x51 nato the std is EPVAT NAAG-LG/3-SG/1, and MPa is 60191 psiįor current 308 win the std is either saami using Piezo SAAMI and MPa is 62000 psi This does not apply to the Steyr Model 1912 Mausers converted to 7.62x51 Nato as those rifles are 98 actions and were completely rebarreled, some with new 2 groove 03A3 barrels. What may have been a good and expedient idea then doesn't mean its a good and safe idea now. When the same old tired argument about 7.62 Nato versus three-O-eight comes up you need to think about now, not then. But what was safe for Chilean soldiers in 1962 may not be safe for JoeBob, father of 4, in 2009. Obviously many of these rifles have survived. The usual argument is: Them thar Chileno rellenos figured it was ok so it must be safe.Īs an expedient procedure for occasional use, maybe, probably. This sometimes happens with mis-matched parts. In some Mausers where the safety is difficult or impossible to set this can be remedied by carefully stoning this camming surface on the safety lever and inspecting and possibly stoning the cocking piece if there's any burring present. When the safety is applied it "cams" the cocking piece back and away from the sear. This shows the safety lever interaction with the cocking piece. IMO the 308 is too much pressure for that action. (this situation can also be applied to 1893/16 Spanish Mausers converted to ~some~ form of 7.62mm)Pretty interesting stuff Dutch. (this situation can also be applied to 1893/16 Spanish Mausers converted to ~some~ form of 7.62mm) Headspace gauges are to be used with a delicate touch, not forced, so that the person gauging may not realize the problem exists. This can cause a false reading with a headspace gauge in that the bolt will stop turning when it hits the high spot, the lip. This lip is at the top of the camming surface as the bolt closes. The reason being - just before the setback recess there's usually a lip. There's more wear and setback on the lower lug race.Ĭan lug setback be detected with headspace gauges? This contrast enhanced image shows a not uncommon malady with some Mausers. I cut the threads off the receiver ring so the bolt lug races were clearly visible. Think about the somewhat increased pressure needed to force that oversize bullet through the neck of the funnel, as it were. Too high a heat will shrink steel, and in this case, shrink the diameter of the bore.

That was the only section of barrel that had this degree of copper fouling on the lands. I had wondered about that until I studied on it a while and realized it was caused from overheating of the barrel when the rear sight base was re-soldered on the barrel. I also noticed a secondary phenomenon out in front of the chamber where the lands are more heavily fouled with copper jacket material. The areas of the solder joint that have no solder were, IMO, eroded away by flame cutting.

When I first removed the barrel from the receiver I'd noticed a silver ring around the chamber.
