[QUOTE="Mikecr, post: 369769, member: 1521"] I log OALtoOGV for every cartridge, and have never had an issue with consistant seating to those parameters. For my measurements, I use a Sinclair comparator(the NUT) and a caliper. After trying many other methods, this is what I came to as being most reliable. I doubt it tells me actual distance from the lands, but that doesn't matter. I tweak seating using the nut. I log results OALtoOGV, and this is always given(on my bench) as a reference for most accurate seated measurement. IMO, pick your best standard and stick with it across the board. As far as seating depth accuracy being important,, I can tell you that I have barrels where it is critical for accuracy. With one(a Cooper/Wilson barrel), 3thou off from optimum means 1/4moa at 300 opens to an ugly 1/2moa. So I care about seating accuracy. Luckily, Wilson dies produce no issue here. Oh yeah, I should qualify, my guns are single shot, and I use relatively light neck tension(no more than needed). [/QUOTE]
