Those photos look like there might be signs of over pressure. Primer edges appear slightly pancaked, although hard to really tell. Looks like some some primer flow evident perhaps and there appears to be a mark consistent with your ejector on the case head. Primer hasn't completely flattened and no signs of powder residue around the primer. I've seen much worse signs on my own brass and never had a jammed round, but every rifle is different. Looking at your bolt face, there looks to be some pitting around where the primer pocket edges are or is this just muck? If pitting, then that's a sure sign of hot gases coming back between primer pocket edges and gas cutting the bolt face. One of my rifles is the same but it has had 20 years abuse!

 

I'd say a hot load probably hasn't helped and crimping is probably raising pressures above where you've been before but hard to say for sure from the photos. If running loads that hot, the last thing I'd be doing is crimping though, especially where I'd not worked up the loads with crimps in place first.

I'd agree with this. That primer has cratered and pancaked. The load needs backing down.
