Tikka T3 Firing Pin Wear

[kit.critchlow]

Hello Tikka users. I purchased a Tikka T3, 6UM from a friend. No idea how many rounds it had before the 6UM. I took the firing pin out just to inspect and clean. It is wearing very badly and I'm pretty sure this is not normal and probably not helping with consistent ignition.

Has anyone seen this? It looks like there must have been a chunk of metal debris in the bolt body at one point. Inside the bolt near the face is very rough. It looks like the reamer they used got stuck or something.

Any thoughts as to how big of a problem this is?
