I heard a song called "The Ballad of Ed Cantrell that led me back to the forum

It brought back quite a few memories. I spent some time out in the desert country and would occasionally see old Eds' horse trailer...
I started out many years ago with a .357 Lee Loader with Unique and and jacketed 125's. I never had a squib but a few primers went off with the hammer and rod set- up.
It's a good little system and I suspect the problem is going lean on the dipper.
