Thanks. That post is somewhat reassuring my instincts.

Like I said, I always use bullets that are the same length. I understand we are talking only thousandths of an inch, but that seems to be what this thread is all about

I mostly load autos, so I am using a TC. Either way, I always thought OAL and case volume dictated pressure more than seating depth. You learn something everyday, right?

I mostly use speer gold dots and Rem golden sabres for reloading, so I do not work with cannelures often. I set my seating die to my desired OAL, which determines case volume, and go at it.
