Hello All: I'm having issues getting 40 S&W rounds to properly chamber in my Bulldog. The moulds I'm working with are the Lee 401-175-TC, the NOE 402-180-RN and the LBT 401-185-RN. The brass is once fired police range and it is passed through a Lee bulge buster before sizing in a RCBS carbide die. It is expanded using a Lee powder through expansion die and seated with a Lee dead length seating die and crimped to .820 using a Dillon taper crimp die or a Lee FCD. I started with bullets sized .401 but have also used .400. Some powder coated and others lubed. For reasons we are all aware of I don't like to deep seat 40 S&W rounds but in dummy rounds I've seated the bullets far too deep and the problems persist. While I'm not a big fan of the "no moon clips" design of the Charter Arms revolver it works okay, if slowly with factory rounds. Summing up. I've tried all of the above to get the rounds to fit. They plunk test in a case gage to the point of being loose and I've tried using a factory round as a guide in setting up the dies. What has me more than a little confused is that about 1/3 to 1/2 the rounds chamber fine and the rest leave the cartridge proud of the cylinder enough that the cylinder binds if it closes at all. and no, the problem is not headstamp specific so I don't think it's a matter of brass thickness. Sorry this is so long winded but I'm temporarily (I hope) stumped. Any ideas? Thanks Gp
