Is Remington Peters brass really that bad?

[TRexF16]

I have 300 Norma stamped 375 Weatherby cases here, the very first 20 I used have primer pockets so loose that the primers fall out as you pick them out of the loading block. They were very tight going in the first time, then ONE firing had them loose, it was not a high pressure load either as I had run the first 3 cases over the Pressure Trace.
I informed Norma, then suddenly 375 Weatherby brass was removed from their list…

Cheers.

I saw a similar thing with Weatherby-headstamped, Norma-made 338-06 brass, but in fairness I was running them pretty hot. More troubling was the neck walls varying by .003" in thickness. I had to neck-turn more than half of them.
My Norma 270 WSM cases are just fine though and holding up. I have five firings on this case, and that includes two big mule deer I've killed with the same case, 2023 and 2024. Gonna give it another opportunity next fall. Pic taken right after 2024's shot.
