I have been using MDs idea on how to make standard sizing dies preform better.
Through experimentation I've found other makes of full-length dies produce very straight cases IF the expander ball's raised to just under the neck portion of the die. I've found basic RCBS dies can be adjusted to do exactly this--though of course decapping the case requires another step (one reason a Lee decapping die permanently resides in one hole of my turret presses).Quote JB
Plus I free float the die in place.A lot of folks think free floating the die means to leave it loose.Not so.You run the case up into the die with the expanding ball loose.As you start the stroke down and the inside of the case neck goes onto the expander ball,you tighten the ball down.The die is now free floated and you can finish your sizing.Yes it takes and extra step of using the universal decaping die first,but run out is at a mininum.I don`t even check the runout anymore as I am not shooting BR.JMHO,Huntz
