Ok, I fixed the high primer problem by running all of my brass through a primer pocket uniformer, it now seats at a consistent .002-.003

All stations are full, but your post got me to thinking. What if the sizer is stopping the upstroke in different places? I'll play with that, I'll set the sizer to just barely hit the shell plate with no case under it like I do when running the RT1500. My primer cup and set pin is clean. I once fabbed a spacer out of a feeler gauge .004, worked great for a dozen or so rounds then it ended up in the indexing innards under the shell plate.

Sorry, mistype on my part. 2.245 to 2.270

I originally posted this on the official Dillon forum but there is more traffic and sage advice here. The primer seating function has never worked on my 750, it seats them flush, will NOT countersink. Oh, and large pistol primers end up on the slide everytime. Shell plate is tight, I have the flat bearing on it. I can live with hand priming but I can't live with the erratic bullet seating depth. 5.56 with a target of 2.260 OAL. It will literally seat one at 2.45 and the next at 2.70. Brass is once fired Lake City decapped, wet tumbled, swaged, induction annealed, trimmed on the RT1500, tumbled, hand primed and ran through the Dillon. Bullets are 69 gr SMK BTHP, dies are Redding Master Hunter but I get similar maybe slightly better results with cheapo Lee dies. Next step I'm going to borrow a mag base dial indicator to measure where the ram stops. I hope somebody here can help me or direct me to somewhere that can.-Rick
