[QUOTE="dmproske, post: 247026, member: 10838"] I am having Lee make me a Collet die for my .300 RUM. They wanted two fired cases and a bullet. They said prolly 8-12 weeks. I am also going around in circles with a Redding bushing neck sizer die. I start out with less then .001 neck runout from a fired case. After sizing with the bushing I get .002-.006 neck runout. Yes the expander ball is NOT in the die. I have tried several different bushing sizes, no difference. I understand that the bushing will push the brass to the inside of the neck, so once you seat a bullet you have bullet runout. What I am talking about here is NECK runout right after sizing the neck and measuring B4 seating!! I would think I should have a straight outside neck at that point. Once my neck turning tools get here I will outside turn the necks, then Lee Collet neck size. Then use the Redding body die when needed. Once I turn my necks I will try the Redding bushing die again & give it one last shot. So far it has been a dissapointment. The redding comp seating die is a nice piece though. [/QUOTE]
