    Speaking of seating dies


    I've used Lee die's Let's rephrase that Lee die's is all I've ever used, been noticing seating depth has not been consistant, not a whole lot but .005 here and there. Do they make a die that will stay guaranteed consistant ? I've made sure all cases are trimmed the same length. Is .005 or so enough to bother with ? Being too particular ???

    Re: Speaking of seating dies

    Is this an OAL case or length or measurement based on the ogive of a seated bullet?

    Measured to the ogive is much more accurate and consistent...OAL can very a bit even when the ogive length is nearly dead on.

    Chance are better than even its not the die.

    Here are a few bullets from the same lot-box, .007" difference in the ogive position/shape. How and where those differences contacts the seater plug will affect the seating depth.


    Other things to watch for is if the bullet tip is bottoming out in the seater plug and any play in the press linkage.

    Lastly, it may not be the measurement, but how its being measured.

    Re: Speaking of seating dies

    worked up a few(3), didn't feel well, rounds today and thought about this thread. out of curiosity measured a small handful, sure nuff .003/.005 maybe .006 difference. I've read where comp. shooter's do this I just never thought it necessary. Thought Berger's were made to better tolerance's and maybe they are, those are the only ones I've measured. Don't think I'll spend that extra $$ for a Forster micro seating die, put it where it will really benefit my grouping ;D

    pull the seater plug outta ur lee die and drop a bullet in it. make sure the plug is bearing on the ogive of the bullet, not the tip. if the plugs bearing on the tip u can drill out the seater plug. have had to do that on a couple dies from various makers.

    First thing I checked when I noticed the inconsistent measurement

    my lee and hornady 308 dies seat within.001 to the ogive using 155 scenars and 175 smks. cant imagine the bergers are longer and pointier - and he says the plugs bearing correctly. i dunno, never not been able to get a seating die to hold OAL to the ogive

    UPDATE on the Bergers. Had 25 left, out of the 25 there were 2 that were not the same measurement. Measuring to the OGIVE.
