Stiller 408 extractor question.

[RonA]

I just picked up my new .375 Cheytac and noticed that the bolt body on the Stiller 408 action is a bit small for the Cheytac case.
My concern is the extractor. Anyone had any problems breaking the extractor where it's undercut on the end?

Thanks.

I've built dozens of guns on the tac 408 action and I haven't heard of any problems of them breaking.
