This will also give you an idea of the low pressures these early actions were proofed at: This link is a good review, the M1895 action described here was so poorly made the receiver seats set back: Post WW1 steel technology advances very quickly and by the time you get to WW2 it is a mature science. People today just do not appreciate how primitive were the manufacturing processes around 1900 and just how limited the knowledge of the properties and characteristics of steel.

Pre M98 actions have virtually no shooter protection features. What is the weakest link?: It is going to be the action.ДЄ M1895 made of modern materials on a modern production line would be as вЂњstrongвЂќ as many modern actions, minus the better breeching methods that protect the shooter from gas escape from a blown cartridge. I have a LOT of mil surplus ammo to burn up first, and then a LOT of bullets pulled from mil-surp ammo to use before I change barrels to one that handles 150gr better.Д«ut, I was curious about if the barrel change might make my gun stronger/safer? And I was only daring to DREAM about raising the 7x57 pressure from around 44K CUP to around 46K CUP, not anything like 48K or higher. Keep in mind I would NEVER dream of even thinking to change the CUP pressure in an 1893. I just feel safer with the 44,000 CUP pressures than I would with a 1893 Mauser.Д«UT, isn't the chamber part of the barrel? And, if so, would changing the barrel increase the allowed pressure for the round or not? I love the model 95 Chilean though, as it has a notch in the action that the bolt drops into that seems to make it a significant step up in strength from a 1893 Mauser that has no such notch to contain the bolt from moving to the rear.ДЄgain, I am NOT arguing that the 95 Chilean's notch makes it the equivalent in strength of the 98 3 tab locking system. I understand that the Model 98/Large Ring Mausers had a 3 tab locking system on the bolt that makes them safer than the 2 tab locking on the small ring Mausers. Or, is it the strength of the action around the barrel/chamber, and the strength of the bolt system? I was wondering if changing the barrel, which would change the chamber, would allow for an increase in chamber pressures?

I also an Adams and Bennet small ring Mauser barrel I bought a few years ago. What I mean is that I have the factory gun. What I have a question on is the issue of what limits the CUP: chamber or action?

I understand that reloading for this round requires a combination that does not generate more than 44,000 CUP, according to most listings. It has been in my family since the mid 1960s, at least, so I know its condition, and has been completely sporterized. I have an 1895 Chilean Mauser chambered in 7x57, with the original barrel.
