. Your cases are .300 Win Mag and by way of comparison, a Hornady once fired case and deprimed measured at .130. Clean the primer pocket first since the residue can account for .002

Hello and thank you for your reply.
I tumble all my brass in a wet stainless steel pin tumbler which cleans the primer pockets so they look factory new.
The primer pocket depth in all the Norma brass is 0.1275-0.1280" deep, including the misfires.
I forgot to mention two critical bits of information, sorry.
I forgot to mention this happened in my Remington brass also, but same rifle. And, I have had at least 1 hangfire where I heard "click" and then a split second later "bang" in the Norma Brass.
