Looks more like a 5.56 extractor to me, not a 6.5 Grendel extractor. Could just be the photo, but the radius of the extractor groove and lip edge are looking a bit excessive to me.
I just compared with several Grendel bolts of mine, and I think your extractor lip corners are biting into the case rim excessively, causing binding as it tries to go into battery.
Are there wear marks on the outside of your extractor by any chance?
There are a lot of brass shavings all over your bolt as well.
Where did you get the bolt from?
I agree with LRRPF52, that extractor is definitely shaving metal off the rim and looks like a 5.56 extractor. It is too far into the radius of the bolt face. You may try marking up the base of a case with a laundry marker and loading it into the chamber. Then look at the bottom of the cartridge for the extractor marks.
