As for the Lee shell holder for the Trimmer - throw it in the trash and buy a K&M shell holder with a hex-head. Mount the correct sized wrench on your table front (mine is open on bottom), holder in cordless drill, tighten case, put in wrench to finish tighten on light torque setting, TRIM, reverse drill, loosen in wrench, do another. Mounting the trimmer portion to table reduces damage to hands after several hundred.
I also send 223 out for full-length resize, deprime, swage primer pocket, trim for length using Dillon Carbide Trimmer, and tumbling for $0.03 each. Recently received 6000 cases back from that resource. He has a Dillon 1050 that has been modified for that purpose with auto case feeder.
