    I am starting to load some 60 gr partitions and am trying to get the correct seating depth. CAOL is varieng between 2.333 and a whopping 2.367. These are all in excess of 2.26 which is the spec. I am giving up for the night so I don't mess up.

    Don,t panic" you are stiii ok.

    If you have access to a NOSLER #5 reloading guide
    there is a complete bullet seating depth procedure
    on page 42 if not try this.

    Take a fired case and with the expander plug removed
    size only about one 1/8" of the neck.

    Start the bullet to be used just enough to hold it in the
    case.

    Then very gently insert the case and the bullet into
    the chamber and close the action .NOTE dont pull the triger
    as this can move the round forward 3 or 4 thousants giving
    you a false reading.

    This dimension is max over all cartrige length with no freebore with this bullet (TO the ogive).

    Now measure overall length of this round case head to buller tip.2.xxx Then subtract your max overall magazine
    lenght and this will tell you how much freebore you will have if you load to a lengh that fits in your magazine,

    NOTE: softnose bullets will allways vary in length thats why
    you measure to the ogive.

    All factory rifles limit overall cartrige length with the magazine to assure freebore, no freebore means higher pressures.

    If you want the bullet closer to the lands you may have to
    single load.

    Remember this dimension will change with each bullet change
    IE:60gr noz par to 60gr ballistic tip, or other brands and
    weights.

    Long winded I know but I hope this helps

    When I did this, I got 2.333 to 2.367 measurements for overall length but it was with the same bullet and case combo. Any other ideas. BTW this is a Savage tacticle 223 1:8 with about 500 rounds fired through it.
