    I might be missing something also but,
    my 155.5 full bore load is set .015 off the lands. I just got a batch of bullet that were .045 longer ogive to bottom of boat tail.
    now if I load them .015 off the lands from the ogive that will keep my overall length the same but will put .030 more bullet deeper into the case.
    won't this change my case pressure?
    Thanks

    Silkrider,
    30thou of of neck tension change with a .308 means nothing. Just as 30thou of actual bearing means nothing.
    Won't affect a thing
    If 15thou OTL initial is tested as best, this equivalent CBTO is a better attribute to focus on. THAT CBTO will matter.
