F. Guffey, I appreciate hearing from someone who actually uses the Piggyback. Maybe we should start a club.
I really appreciate your mention of the powder lock-out die. I was clueless about this, so Googled it up and learned. I think I'm gonna have to have one. I haven't had a problem (yet), but peace of mind is worth whatever the thing costs.
NOW--- do you have any problem in the priming department? I have a glitch where the spent primer apparently sticks or crimps on the decapper pin occasionally, and then re-starts itself in the primer pocket on the down-stroke. It is then carried to the next station,(priming), and reseated, leaving that case with a used primer.
The fix would be to somehow get the spent primers to reliably drop away from the decapper pin. It's a very simple but frustrating problem, and may be happening in other progressives as well. Any suggestions would be appreciated. jd
