You would think that Remington would put a "caution" on the 6-1/2's to make folks more aware of the potential issues.

There is a caution on the boxes sitting on my bench.
It reads, "
WARNING: Do
not use 6 1/2 small rifle primers in high intensity rifle cartridges such as the 17 Rem, 222 Rem, and the 223 Rem. Damage to your firearm and/or serious personal injury may result."
I bought a bunch during the first shortage and shoot them in my 9mm.
