Re: 7mm rem mag problem
if they are loose its because the neck wasnt prioperly resized, if you sized your brass correctly the neck should have been tight all the way to the shoulder. My guess is your sizer die is not set correctly and is only sizing a small amount of the neck at the mouth and poking the primer out...

Re: 7mm rem mag problem
By some odd manufacturing defect you bullets could be out of tolerance or got mixed up at the factory, check you bullet diameters with a caliper and verify they are correct and a consistent diameter.
