Actually Gene there is a micrometer heat for the Wilsons, but I see little advantage with it. I simply use the shim pack kit to alter my seating depths. Some think the shims are better; I won't go there.
I use mostly Forster seaters, and my Forster press I can see about .0005" max difference using a Forster full length die. If I simply neck size off the Wilson/K&M I see little if any difference in calibers that range from .222 Remington to 6mm Remington.

Gary - I use shims with the Wilson seaters also, but I find the Redding Comp dies can be ajusted down .001" at a time, and are therefore more accurate. I have had some pretty large base to ogive differences with the Wilson.
The best buy on a F/L sizer die is the Harrels. Send them $60 with two fired cases, and you get a die perfect fit for your chamber (in less than 2 weeks). Gene
