Problem with sizing/decapping die

Ok just got my XL-750 set up but still waiting on the 45acp die set. I have a RCBS 45acp carbide die set that I installed until I get the dillon set. For whatever reason the case doesn't go into the sizing/ decapping die I have to use my finger to get it to go in. Is this normal with a die set that's not dillon? Does the RCBC 3 die set not work on a progressive press?

RE: Problem with sizing/decapping die

Dillon dies have a larger radius to make it easy for the case to enter the die on a progressive machine. I've had the same issue your having with Lee dies if the case isn't fully inserted into the shell plate. When loading 9mm using mixed headstamp my Dillion dies were giving me bullet set back so I faced off about .020" from the mouth of the sizing die. The cases now go into the die .020" deeper and grip the bullets tighter and no more set back issues.
