I've had more misfires out of Remington ammo than all the others combined by a factor of about 10X. It's the reason I don't use Remington primers in anything. I've had a couple of misfires out of CCI primers, but nothing like the Remington factory ammo. My hunting loads all use Federal primers even if another brand gives me slightly better accuracy. I've never had a misfire out of a federal primer.
