[QUOTE="DT400, post: 1691107, member: 76847"] Hey all I have a question. I am using Hornady 140 gr 6.5mm SST #26302 and am having serious inconsistencies in seating depth. To the tune of .025" ish. I am using the Lee seating die on a full frame single stage press, it isn't the press for sure. Where the seating stem touches the brass is just past the poly tip/copper joint. If I pull the seating stem from the die and measure the top of the stem to the base of bare bullet I get a variable of .025" or so. If I use a Hornady .22 cal bushing and comparotor base the variance is reduced to about .004-5" If I use a .264 comparator bushing I get a variance of about .0015. Based on this I am finding the dia of the bullet where the poly tip goes in and the seating stem contacts the bullet varies causing my problem. I used these same methods of measurement on Hornady 123gr 6.5mm SST and the Hornady 143 gr 6.5mm ELD-X and these bullets are with-in .002 total variable or less at all 3 points measured (poly/copper joint, at a .22" die and at the .264 ogive die) so I am 99.9999% sure it is the bullets. I emailed Hornady over a week ago and haven't heard form them yet. And in case your wondering the poly tip isn't bottoming out and the stem touched the bullet verified using a black marker witness mark method. Is anyone else having issues with these bullets? It wouldn't be such a big deal if they didn't shoot so well once I seat each round individually by adjusting the seating die for EACH round.. Thought? Any other things I might be missing?
