NC, Thank you for replying, I appreciate the thumbs up from Bill Norris & Mike Ezell as well, looks like .104 it is!

A .104 works pretty well with several bullets in that long neck of a 6br. Go to bergers site and look at their tech specs for all their bullets. IIRC, ya might have do a little math on your own but the bearing surfaces on several 6mm bullets from 80-105 grains that have a similar bearing surface length. But mostly, that long neck is pretty forgiving. I've got a .098 reamer that does well too. Flip a coin between it and a .104.

I’ve shot 1-8 twist .093 & .104 FB with 90 gr Berger, both length shoot fine although my preference is the longer 103-105 gr. Seated inside the lands.

Not 1 thing wrong with that. After a few rounds it will lengthen to .104 anyways. I would say a little shorter freebore is a good thing
