You want to contact Desh. He’ll sort you out. Here his site. https://deshind.com/2017/09/04/savage-bolt-bushing/
Cratering is nothing more than a visual annoyance, but before you bush the pin, try re-contouring the pin tip to a larger radius.
It’s only a problem if the striker pin is too pointy allowing the radius to sit below the surface of the pin hole. This allows the pin to move laterally causing primer cratering/smearing. If your primer strikes look ok, it’s fine.
This is a perfect striker pin shape & protrusion. If yours looks even similar to this, it’s in fine shape. If you are able to post a picture we can tell you how it looks.

Ever consider it "could be" a brass problem and NOT a firing pin issue? Brass too short for the chamber, when fired, primer tries to back out of the pocket, gets "cratered" and pushed back into the pocket? Just thinking out loud.;)
There is that. Yeah, I’d take care of it. I did by way of a a PTG bolt head & still happy I did. Bushing works well, it makes the Striker more efficient & Desh does an amazing job. You won’t be disappointed.
Dave, are you saying that PTG bolt heads are made to specs that don't require bushing using Savage OEM firing pins? I thought I read something somewhere about PTG bolt heads in regards to this issue, but I can't find it.
The PTG bolt heads are machined to tighter specs. They have fixed cratering conditions for some. But so does bolt bushing. And at much less expense. Also, the PTG bolts heads typically need to be fit. And then headspaced. I didn’t by a rifle & start changing things out. I built my Savage from the start because, well, that’s what I do. I also machined a firing pin striker to fit perfectly. Everything about firearms is hobby to me.
I’m not trying to discourage or encourage. If trying to fix a potential problem, there are more straightforward ways. And if it’s hobby, I don’t have to recommend either way.
I understand what you're saying. I use PTG bolt heads on a 6br and 223 that were installed prior to headspacing aftermarket barrels. Neither rifle craters primers. I wouldn't replace bolt heads to solve a cratering problem. I'd get the bolt head bushed as a first measure.
Thanks everybody. I sent my bolt off just now.

Didn’t know he was having problems. Anyway, for those wondering, here is Desh so he’s not just a name to deal with, LOL!

You will find an improper spring will do this. Even to light of spring. I had alot of crap wrong with my gun to sort out. Still not done. But closer. OI bought parts from gun shack to start the repairs per Dave. CZ where are you at in WY.
Grimstod is another if you're so inclined to have one bushed. Can find him on Accurate Shooter site.
Grimstod & Desh are actually the same person. Grimstod is Desh’s forum handle. He was here in like 2018 & only posted a few times as that name. Desh Industries is his website. He started after getting his Savage Axis & loving it. Phil, the video I linked in post #19. That is Grimstod/Desh. His name is Ben.
FWIW, I've had several guns that cratered primers, pistols and rifles. Unless I went over max loads they never pierced the primers. No, never had them bushed either.
