As the title states......is the M1895 Chilean Mauser rifle considered to be safe when firing the standard 7X57 ammo that is available from commercial sources such as Remington or Winchester? I picked up a nice , all matching ( including the cleaning rod ) one today. I believe this to be one of the "as new" ones that came in the country in the late 60's or early 70's. No import marks.
Yes!
Thanks
If anything US ammo is loaded milder then original military for these rifles. The difference in safety with these older models and the 1898 model has been greatly overrated, after all Mauser wanted to sell the German military new rifles, not to mention foreign contracts.
You8r '95 will handle any ammo you can buy. It is basically the same action as the M96 Swede. which eats hot Norma loads and spits the brass out afterwards. In fact, chances are your rifle will shoot its best with hot loads.
Good luck!

Keep the pressures of your loads equal to or less than the pressures of the original military ammunition.

Kunhausen shows similar numbers in his book : “The Mauser Bolt Actions, A Shop Manual”Quote:
Ludwig Olsen :
Mauser 98 actions produced by Mauser and DWM were proofed with two loads that produced approximately 1000 atmosphere greater pressure than normal factory rounds. That procedure was in accordance with the 1891 German proof law. Proof pressure for the Mauser 98 in 7 X57 was 4,050 atmospheres (57, 591 psi). Pressure of the normal 7 X 57 factory load with 11.2 gram bullet was given in Mauser’s 1908 patent boot as 3,050 atmosphere, or 43, 371 pounds.
While many Mausers in the 1908 Brazilian category will likely endure pressures considerably in excess of the 4,050 atmospheres proof loads, there might be some setback of the receiver locking shoulder with such high pressures
Rifle & Carbine 98: M98 Firearms of the German Army from 1898 to 1918 Dieter
M98 Mauser service rifles underwent a 2 round proof at 4,000 atm gas pressure, 1 atm = 14.6 psi, 4000 atm = 58, 784 psia. Page 103. A comment on the metallurgy and process technology of the era, Dieter found records that indicated that the bolt lugs broke on 1:1000 of GEW98 service rifles used by the Bavarian Army Corp!
Gun Digest 1975 has an excellent article, “A History of Proof Marks, Gun Proof in German” by Lee Kennett.
The article indicates it was applied to the 1898. The 1939 German proof law called for proof at 130% of service load pressure. From Mauser Bolt Rifles by Ludwig Olsen, page 134, The maximum working pressure of the WW2 German 7.9 sS cartridge was 46, 926 psi. Pressures had gone up a bit, but so had metallurgy improved.Quote:
“The problem of smokeless proof was posed in a dramatic way by the Model 1888 and it commercial derivates. In this particular case a solution was sought in the decree of 23 July 1893. This provided that such rifles be proved with a government smokeless powder known as the “4,000 atmosphere powder”, proof pressure was 4,000 metric atmospheres or 58,000 psia. The 4000 atmosphere proof was standardized for the 1893 and continued after 1911.
If you research it, the normal operating pressures of the small ring Mausers were the same as the M98 Mausers, which was 3,050 atmosphere, or 43, 371 pounds. If you exceed that in handloads, or commercial ammunition, whatever happens afterwards is unpredictable.
