[QUOTE="Jud96, post: 2008695, member: 69478"] I’m not arguing, but you realize 200 rounds in on a mild cartridge will have throat erosion. You may not have to adjust your CBTO, but you may have to in order to keep your groups very small. There’s some data out there that supports finding a consistent seating depth node that will keep your groups in the same point of impact across .010-.020 of throat erosion. I have tried that method some, but haven’t gotten the smallest groups with it. To me, if I notice accuracy loss, it’s simple enough to adjust the bullets a few thousandths until the groups shrink up and call it a day for another 100+ rounds. [/QUOTE]
