You are making a mountain out of a mole hill because you do not understand these pressure readings. So let me put it to you this way. YOU DO NOT NEED TO! PERIOD!!!

Ammunition is loaded to SAAMI specs. PERIOD! Unless a box of ammo EXPLICITLY states, on the box, that the rounds are loaded to "+P" pressures, then you have nothing to worry about. Take the damn thing out, buy some Winchester 'white box' .308 147gr FMJ ammo at Wally World and go shoot and enjoy your rifle. When they did the arsenal rebuild on your rifle, the rifle was PROOF tested to pressures higher that the SAAMI spec as a precaution. All arsenal rebuilds are handled this way.

Forget about PSI, CUP, LUP and anything else pertaining to the ammo spec as all ammo is loaded to SAAMI specs and is safe in your rifle. If the barrel is marked 7.62x51 then it was pressure tested to greater than NATO SAAMI specs. If it is marked .308 Winchester, it was pressure tested to greater than .308 Winchester SAAMI specs. ALL ammo manufacturers load ammo to SAAMI specs!!!!!!!!!!!! Some niche ammo manufacturers load ammo to '+P' (higher than SAAMI specs). It will be stated as such on the box. Do not use +P ammo in your Mauser!

I hope you will take what I have told you and forget about all the crap that you are trying to ingest about things you do not understand and are obviously causing you to not enjoy that 1893 Mauser as you should be. I have two 1893's and enjoy shooting them. Of course, I reload, but I make sure that the rounds are loaded to MINIMUM SAAMI SPECS!

Now, go to Wally World, buy the ammo I stated above and have fun with it. You have a perfectly good weaqpon and should be enjoying it rather that delving into all this crap you do not understand. It will NOT blow up on you unless there is a barrel obstruction or if you give it a steady diet of '+P' ammo.

Nuff said.
