I find John provides info when it is needed. I did need to read this.
I once accidentally used CCI pistol primers while developing loads in a .270- ignition was poor( of course) and the primer strike perforated the primer.
I had purchased 4 and within the taped package , was the no good pistola primers. I seated a few( mistakenly) and then decided to give them a go.
A few ignited the 4350, a few didn't and perforated the primer.
CCI pistol primers were packaged in blue and white slightly different than LR primers.
Anyways, I digress, John keep doing what you do.
Love you stuff
