Re: .223 Cratered Primer Pockets with Factory ammo?
They're scrap brass if the primer won't stay put.
I used a box of "Superformance" 223 last summer and the brass was beat up pretty bad after the first firing. I was able to resize/reload them 2 more times with a Varget/ 52Gn AMax load my gun likes. After the third firing, most of the cases were done with splits and cracks. They all went in the scrap pail.
