Chilean Mauser ruptured primers

For my education what do you mean by ? blanking ?

Look how crisp the outer edge of the firing pin strike is.
The crispness of the primer edges both around the firing pin strike and the outside edge of the cup are signs of the pressure that was inside the case.

I have the same weapon, I think. Chileo Modelo Model 1898 Crest stamped 1912.

Same name, [Mauser] diff model. OP,s is a small ring Md 1895. IIRC made by either LOWE, or DWM in Grmany.

Yours is Large ring model 98. That the Chileans got from Steyr in Austria. They switched from the 1895 to the 1898 in 1912, and call designated their rifles as Md 1912s.

[Flouncer]

Yes. Neglected that mine is a Steyr. Nice catch

OP, was there any extraction difficulties, like overly hard bolt lift? Or having to jerk the bolt rearward?

No issues with extraction/ bolt manipulation, real smooth. I did have some pressure blow back on my thumb a couple times when the primers ruptured. I'll try to check FP protrusion tomorrow, and noted S&B is typically hotter. Probably will grab a box of something else to try. Regardless it shoots great and I'm planning to take a deer with a 129 year old rifle

He can twist the firing pin at the cooking piece so it is in the fired position and measure the protrusion by standing up a caliper at $10 from harbor freight as a depth gauge.
I believe Dave Kiff at Pacific Tool sells the actual tool.
He can use a feeler gauge and some modeling clay to get a good enough for government number as well.
My best guess would be a pitted firing pin.
