Ive found federal 215 and Winchester mag primers are noticeably more consistent than Remington's
I gave up on remington primers as I was getting hang fires in sub zero temps , when used in my 340 wby.
and have never yet had that issue with federal or winchester.
I use a RCBS hand priming tool where I can feel the primer seating all the way in so I'm not sure if that's the case Nomercy. And Hardcast I had the Rem in my ammo box for a long time (my old stock) . I always use CCI200s and never had an issue. I loaded up a box with the CCIs and will take it out again this coming week.
One other thing it could be is a sticky firing pin in the Encore. I'll take it out and check it over. I'm going to be replacing the firing pin return spring anyway.
