Help with seating my new Lapua Brass properly

[Bc'z]

Base to ogive measurements should be generally similar for a well tuned 308 and target ogive bullets. Changing brass may move the tune for the seating depth, but it typically doesn't move more than a few thousandths.

Brass volume changed his tune

A stable seating depth tune will typically hold up over obscene speed changes. Brass volume is not enough to change that. Might want to consider other factors.

We dont really know how stable it was to begin with...but yea i get it too.
It should not change much...however adjustments in seating will help get it back followed by
final powder adjustment if needed.
