Micrometer Seater useful?

It most certainly will. One of the advantages of the Lee seater is you can remove the seater stem and use it along with your vernier to measure the CBTO

Not arguing here. Just a question. Should sorting the bullets by measuring from the base to the ogive help in this regard?

It would. But what are you going to do with the ones you deemed "out of spec"?

But seating stems do not seat off the ogive. They seat down from the point. And if your BTO varies, it is not giving you a true measurement from the ogive which is where the bullet contacts the lands.

In all honesty, the Hornady or Wilson comparators don't quite measure from the ogive, but very close. Much more so than measuring with a seating stem.

The #'s I get when using the Lee stem are more constant from round to round that when I use my Hornady CBTO tool. I guess you could say the # is more of an OAL than a CBTO.
