Glad to hear that you fixed the issue. That said, Remington primers seem to have soft cups compared to CCI, and Federal.
I’ve tested their primers again recently and they’re usually very flat, and look like they were almost going to go through the cup. Those were BR 7 1/2 SRP. CCI BR and Federals would always hide the fact that it was a near max load.
25.3 VarGet behind a 73 gr. Berger BT in Lapua brass in a Remington mil-spec rifle. So much so that after I tested those REM 7 1/2’s and CCI -400 vs the Benchrest and FGMM that I lowered the charge down to 24.2.
I’ve had bad luck with Remington primers over my lifetime with FTF, and for that reason never really wanted to use them. But your results may be different.
The cup material and thickness has been the issue for me.

Years ago I experienced this problem. It was with military brass reformed to .243 Winchester. I'm sure my problem was due to lack of knowledge on my part at the time. In those days I thought brass was brass and didn't understand the differences in case capacity, neck thickness, etc. After two shots I didn't try anymore. The remainder of what I had loaded still sits on a shelf in my loading room, as a reminder of what can happen.
