Cause of stuck case?

[nikonNUT]

Afternoon all,
Went to the range today and decided to try out the Hornady Match 120gr ELD-M ammo. I got 2 stuck cases in 20 rounds and it was easy enough to clear the issue (popped the scope off and mortared the gun lightly) but any ideas on the casue? I'm thinking not enough gas as the 147's I shot yesterday functioned perfectly but I wanted to ask the gurus. Thank you for the input all! Tight groups!

Not enough gas? No, way too much gas! Notice the scrubbing on the case heads or web area?

Yes, sir! And split cases at the neck. I'll turn her down and try again. Thank you!!!

EDIT: Holy shit! The gas block was opened up 28 clicks. WTF Savage?!?

Would've been more informative to leave the scope on and check zero after mortaring.

I'm running a Vortex QD precision mount. The nine shot group measured .821 MOA with 2 case (and scope) removals mid string but I will be re-zeroing next weekend just in case.
