[QUOTE="Fitch, post: 370138, member: 19372"] We can agree to disagree. :) But I will explain what's behind my comment so you can help me understand where I'm not understanding this correctly. The bullet is only so long. My thinking is that when the distance from the base increases, the distance from the tip decreases. That means the seating die will position the ogive contact location closer to the lands unless it only contacts the bullet at the same diameter the lands would. I don't know any way to adjust the seating die to seat only with contact where the bullet will contact the lands which is the only way a die will give the same cartridge base to ogive contact distance. And if I could get the die to push there, I'm not sure that is a good idea. If you have a way to have the seating stem push on the bullet at the land/ogive contact ring with out damaging the bullet, I'll give it a try. I use the Sinclair tool which measures the distance to the base of the cartridge and the base of the bullet when it is touching the lands from the same reference surface. The difference in those distances is the base to ogive distance of chamber in that particular rifle. I use that distance and an average bullet to set up my seating die. Try as I might, the base to ogive distance doesn't come out identical on each loaded round - there are variations of a few thousandts. If I sort the bullets based on base to ogive distance the variation is reduced. Unless each individual bullet is adjusted for base to ogive distance, or the seating die touches the bullet ogive exactly at the same location the lands will, there is going to be variation induced by variations in bullet geometry. I must be missing something here. What is it? Fitch [/QUOTE]
