Diagnose my ammo problem...
I took the 260 out today to try a few different loads from Southwest Ammunition (I still don't reload, yet). Two of the loads did fine. When I was trying out their 136 grain Scenar-L, I ran into a problem closing my bolt after a few rounds. I finally found that a primer had come out of the case, and was blocking the bolt lugs from rotating into position. When I inspected the brass, I found that 4 of the 10 rounds I had fired of that load had either bulging or missing primers. The brass from the other two loads (139 Scenar in Lapua brass, and 142 SMK) were just fine. I shot the 142 after this load, and there were no problems. Seems like this ammo is loaded too hot? I've had good luck with this company in the past, but am reluctant to shoot more of that ammo. Of course, I have over 200 rounds of it...
Here's a pic of what I was seeing. Recommendations?

My buddy had some 308 that the primers fell out of. They weren't loaded too hot. The primer pockets were just too loose.
Check that before you assume they're loaded hot.

That's what I thought too. The primers look perfect.

Look up case specs for the primer pocket. Measure that. But I'd agree the fired cases with primer issues are out of spec.
