Sub'd. I've been thinking about buying one of these jigs. A buddy of mine was talking about getting a mill. I'll tell him to hold off until you try the jig out.
I really like the aero lowers.
OP, a pair of vice grips with the jaws wrapped in electrical tape and some painters tape to put around the holes will be a big help.
MIdway had a sale on cci primers with free shipping and no hazmat. You had to buy 5k.
MidSouth Shooter Supply runs shipping sales on primers and powder also.
