When you close the bolt handle down the extractor should slide around the rim about 20 degrees.
There shouldnt be a mark either where the extractor slides over the rim when just closing the bolt. their shouldnt be any marks or scrapes anywhere.

Did you get that M2 ammo at a gun show? I wonder if it was reloaded ammo.
Now you see why I gave away my milsurplus ammo?

To yank a bullet out a case takes some doing. LOL!
