I finally got around to shooting my Springfield M1A. Just to check function. Shoots great. Very pleased with it. I picked up my brass in the off chance that I will reload some day. I noticed they all had similar dings on them. I'm not overly concerned about it but I don't know if this is normal for these things. Gun is brand new never fired Springfield M1A standard model.

M1A brass damage

Did you look at the bolt face?
If brass is getting dinged, there's going to be a brass mark at the ding point. Use a good flashlight and inspect it.
An extractor usually dings the forward side of the rim, usually caused by a tight chamber, an over gassed gun, or hot loaded ammo.
What is pictured is minor.

I'm thinking it's the extractor. It does have brass marks on it. The bolt face as well but not in a way that is consistent with the marks on the casings. There are also some brass marks on the the deflector. That could be part of the issue. I don't really have any experience with this rifle other then throwing some rounds down range yesterday. As I said I'm not terribly concerned since it functioned fine was just being curious.

The bolt face with all the brass that is deposited on it is just indicative of soft brass. The ding marks are probably also because of soft brass.
The bolt rotates as it's locking up and unlocking and that is what is "painting" your bolt face around the center surface.
I'd be curious to see what that bolt face would look like after cleaning it well, then firing some Lake City ammo which has a bit harder brass and leaves less deposits.
I've encountered that type of bolt face brass deposition with CAVIM 7.62x51 ammo as it is softer brass also. You can tell immediately when reloading mixed brass when a CAVIM case enters the resizing die.
So far, not seeing anything that appears to be worrisome.

My M1a beats the shit out of my brass also. No big deal, i just reload it as normal....Just keep an eye on the cases for the telltale case head seperation ring, and case neck cracks.
I haven't shot my M14 in quite a while, but I'm seeing firing pin "cratering" on that case (the OP's). That's when the firing pin hole in the bolt is just a little oversized and the primer cup "flows" back into it upon detonation.
Not a big deal; I just don't remember ever seeing it on my 308 brass.

Yes, a slightly oversized firing pin hole and maybe a soft primer cup.
I'd like to see results of some good military ammo with harder brass and primer cups fired from the OP's gun. I'd venture a guess that the brass deposits and cratering would be minimized greatly.
Or brass shot out of an AK47 !
My sks tears up brass as well. Mostly because the rifle ejects brass straight up with authority and they bounce off the outdoor range overhead ceiling or fly out onto the gravel after falling 20 feet from the air. Lol. The brass always has big dents in it.
FYI, i fabbed a cheap brass "buffer" using electrical tape on the back edge of the dust cover. Works awesome minimising "AK brass dings" . I can post a pic of my Opap if you want to see how i did the mod.
