[QUOTE="Needbacon, post: 2142837, member: 109803"] Gotcha. So I think I'm doing all that correctly, I just didn't have the vocabulary to ask my question accurately. My OAL guage put my lands at 2.371 when I checked last year. I started seating all my bullets at 2.291 CBTO because I found that was what grouped best. I make sure all my bullets are seated at this CBTO before I fire them and it works great. Then I bought some Speer 145s, decided to try them at 2.361 CBTO to start and find my powder node. Well, when I cycled them they had marks from the lands on them. So I ran the OAL gauge again and it put my lands closer to 2.338 using the Speer bullet. I guess what I'm asking is, I wouldn't think my lands would move, so is that maybe due to fouling? Or would my CBTO length to the lands change with a different bullet type? I'm just kinda confused on why I would get a different measurement to the lands and I need to make sure I don't do something I'll regret here... [/QUOTE]
