That just plain sucks! I've been using Remington's CoreLokt's to take deer and target practice for years and I've been lucky enough to never have one misfire with 'em in any of my rifles. Wolf ammo on the other hand I've had 3 misfires over the years, but that's another story. I really think it's horrible that Remington would let something like that slip through the line and end up on the shelf. I've always given the bullet the once over before hitting the field but I think from now on I'll be checking that primer too. You should contact Remington and make them aware of the problem.
