Coned bolt on a Savage?? Anybody ever consider it?
Single feeding a short fat round, bullet point hits the tenon face before it starts into the chamber. So, you have to point the round up and into the chamber before you think about closing the bolt.
So, "coned bolt and barrel face"?
Only issue that comes to mind is the extractor slot in the bolt head.
Lugs are 0.451 deep, only about 0.165 of the extractor slot that isn't taken up, being used.
Maybe taper the back of the extractor to match the angle of the (coned) bolt head without getting to the ball hole?
And this would be \on the smaller bolt head. (.223 size) Not enough extra meat on a larger bolt face. (.308 size) And this is for single feeding.

And by the way: MERRY CHRISTMAS.
