You didn't say if it is a Savage or aftermarket. Due to cratering I replaced mine with a PTG for $54 from bullets.com; no more cratering and clearly a higher precision part.
A couple notes on this...
1) if the bolt head is not from a Target Action in the last few years, yeah, I'd get a new one for sure. The manufacturing process went something like: Savage machined the bolt head to spec, then a sub-contractor did the hardening, then Savage put them in a gigantic rock tumbler to polish them up, and then if applicable coated them. Problem is, thats why they tended to have rounded corners, edges... and sometimes dished bolt faces, in extreme examples (maybe someone left them in the tumbler too long?

). After a lot of prodding, they changed the process for the parts used on the 'precision' guns somewhat - they machined the original to rough dimension, and then *after* tumbling, they would remachine the critical surfaces like the bolt face, back of the lugs, etc. to final spec. Much better!
2) I like my PTG bolt heads... but they ain't always perfect either. I had one gun that I had fitted with a no-nut barrel (first mistake), with a PTG bolt head with no ejector. Then, decided I really, really wanted an ejector for team matches (coaches get grumpy if they're waiting on you to fumble around with cases when they're ready to send the next round). I 'knew' I needed to check the head space, so I tossed my GO gauge in... perfect. But then I found my seating depth was way off - like 6 thou. Started checking the new bolt head... everything was perfectly in spec, bolt face was 0.125" deep, etc. etc. Hmmm... went and checked the 'old' bolt face... ah-hah. Turns out *it* was out of spec - @ 0.119" deep. That little aw-$hit cost me a whole bunch of headaches. Everything worked out in the end, but the moral of the story (beside no-nut barrels are evil

) is that just because the part is aftermarket, doesn't mean there isn't the occasional screw-up that makes it thru to the end user.
