    Sounds like you had some loose primer pockets. If the primer goes in too easily, I toss the case. There's nothing you can do to fix that and if the pocket is loose that usually means the case has seen excessive pressure or has been reloaded to the end of it's lifecycle.
    Luck favors the prepared.

      I noticed youre using Lake City Brass
      Did you have any primers go in with a little more force than usual, sometimes when military brass is not swagged (military brass has a crimp on the primer pocket, if the crimp is not removed properly "swagged") it could damage the new primer when trying to install it, compare some military brass to factory and you can see the difference on the pocket

          Solution is to swage all your brass.

            yes also noticed that some were hard to get in. Guess i will look a little closed next time I prime. Its a learning curve, just need to find out want to watch for and get a better feel when the primer goes in. If it goes in to easy, I will toss it out. Seems like a go/no-go gauge would be good to have/use.

                Agreed. If they're loose pockets, toss them out. I was referring to the case where the pockets aren't loose and you don't want to sort the brass between crimped primer pockets and non-crimped?
