After noticing that I was getting inconsistent oal or base to ogive measurements, I pulled the seater plug out, blackened the tip of a couple bullets, hybrids and Hor. AMP hpbts. Then turn the bullets inside the seater and see where the contact patch is on the bullet. Now measuring from the ogive to the bottom of the contact patch it's anywhere from .202" to .225", it's actually closer to the tip than it's from the ogive, Tubb mentions in his video they modded the 308 seater plug to be closer to the ogive, something is not working here. And, my Hornady seater plug makes it's own contact patch just a couple thou higher than the Redding modified plug. The bullet on the right is the Hornady, contact is made even higher on that bullet.
