Feathermax, I agree with Rocky.
I've been reloading since the '60's, and my view of seating depth is this:
1)Seat the bullets so they fit through the rifle's magazine.
2) Check to make sure the bullets aren't touching the lands.
3) worry about something else, like the worldwide gnat shortage, or Alaskan putty tariff policy- something relevent like that.
IMO, seating depth can help you tune an already good load, but fiddling with seating depth is vastly overblown.
