Yes you are right, and it does in my 6.5 x 55 - but you see, that I have to set my 308 win. back .009" to get .001 necktension. If I neckturn, it will be even more, and when it is well known, that more setback than .005" can give you problems - as I found out
Funny thing is, fired they are round (the offset is inside), and when necksized they have .002 runout on the neck, but sub .002 on ogive, when loaded. This is something i would expect from the Lee collet die !! - not from a bushing die !!
