So I have been scouring this site reading every thread I could find about bushing dies and expander balls and I finally broke down and bought one and a comp seater. As I read more I started reading about run out and using 2 bushings to step down the sizing to prevent this. So here is my game plan and I am soliciting your opinions to make sure I am on the right track. So my fired case neck measures at .277 (.243 win) and my loaded case neck is .271-.2715 so I ordered the .270, and .269 bushings for use in my FL die setting my shoulder back .001-.002. Now I just ordered a Neck bushing die to use to step down the neck to help minimize runout, I plan to use a .273 bushing to step it down which would give a .004 - .003 step down each sizing. Does that all sound about right? Also I do plan to use the carbide expander ball an yes I know it can add to runout but I do believe the neck ID is more important than the neck OD and since I don't neck turn I believe just kissing the inside of the neck with the carbide ball makes more sense and that is why I want to limit runout as much as possible in the other steps . Does this all sound like I am on the right track? Or am I off on my thinking?
