I have owned several model 10/11/12 rifles. All have the same bolt head. Ejection issues haven't followed the cartridge and these issues are well known in the shooting community.
That said, it isn't generally a deal breaker for a target gun and there are remedies and aftermarket options to alleviate the issue.
I think I had to add a stronger spring and new extractor to my 308 and a 223 now that I think of it. Possibly a ball bearing in the ejector hole hole too but can't remember anymore.
Either way, the issues can be remedied and I still prefer the savage bolt design over the remington 700.
Fit and finish on savage is all over the map lately. But again. Not usually a deal breaker.
Just my opinions and experiences. Take it for what it's worth.
