Not too much powder, or to put it another way, normal, to almost lighter pressure., going by the way the primers have not flattened much.

Small, sharp firing pin, large firing pin hole.

Bad firing pin fit, weak mainspring?
Rifle really needs attention.
Not over pressure, as mentionned, primers aren't flattened.

Thought it was pretty weird. I'd be concerned if I EVER saw that coming from one of my loads. I didn't even want to reload them, so I made a little pile of them on the bench for the next guy to check out....

Firing pin hole is much too large for actual pin diameter.
A weak firing pin spring exacerbates the problem, so another possible factor.
Pressures appear rather normal, otherwise.

Several Robarm XCRs do that. On some primers, they will flow way back into the piling pin hole, on others, they will puncture. Alex's "solution" was to debut the firing pin hole with a drill bit.
