Gas ring condition?
Gas rings properly staggered?
Gas key tight?
Rifle well lubricated?

Entirely possible the rim/casehead of the cartridge is slightly oversize/out of shape. This can prevent the bolt from closing if the extractor is too far "open". It can jam the bolt closed as well if you force it closed.

This is the third occurrence of Federal ammo issues I have heard of in two weeks. One was a couple of fired cases sticking in the chamber.
I would not surprised if there is a run of the Federal with out of spec casings.
