I recently acquired a 12 VLP in .223 and I have been working up handloads. When trying to determine bullet seating depth I went to someon who has a Hornady Lock n Load Overall Length Gauge tool. For Sierra 69 grain HPBT Matchkings we got a reading of 2.175 " to the lands, and with Sierra 53 grain HP Matchkings the reading was 2.160. This seems very short for the .223 which has a maximum OAL of 2.260. I have had no trouble shooting factory ammo with OAL greater than the readings we got. Seems to me we may have not measured it accurately.
Do these measurements sound right?
