DAL - There's no need to be extremely cautious and fear a primer detonation. Take safety precautions, of course, but don't fear the process. As anyone who has used the old Lee Handloaders will attest (I'm sure Paul B. has used a few at one time or another since he still has the decapping pins
), you're going to have one go off eventually. It startles you, but it would be very rare to have anything bad happen.
So tell us, are you still just sitting there staring at it? We need a little feedback here.
