Another option, since you have to set up your correct die anyway, just run them through the proper die AFTER you set it up and load another 6 rounds. I use such ammo for practice, but you will not want to chrony them due to difference in neck tension. The OAL may shrink a little, but will be close enough to shoot. You could also tap them once or twice in a kinetic bullet puller to push them out a little, and then seat in the correct and adjusted die to have them come out correct OAL or as close as possible without pulling. Its not perfect, but you likely won't see a difference for practice ammo. Have had to do this a few times when I overadjusted a seater die. You have to really seat a few bullets anyway to have an idea where the correct setting is as most have enough variation in OAL to throw you off if you start out with a small batch and end up short or long on the average when setting up for a different bullet.
