    got a lee decapping die in high hopes of using it to decap a bunch of crimped milsurp brass and run it through the dillon rt1200 case trimmer. damn thing just refuses to deprime any crimped primers. the decapping stem just gets pushed up into the die body.

    if your looking for a good strong decapping die the lee isnt it. i like leed dies but their decapper just plain sucks

    Jon,Tighten down the collet nut on top,and it should stop the decapping pin from moving.

    I've never had any problems decapping crimped primers with my Lee dies,but have broken countless RCBS decapping pins by accidently trying to decap a crimped primed case with them.

    I did. After it pushed loose the first time i gorrilla armed that thing tight as i could get it. No beuno. Two wrenchs and used a hammer to put a few love taps on it the third time. Just gave up put my dillon size die back in. Just ended up sizing twice.

    Now thatthey are all decrimped ill use the lee going forward in that setup.

    I hate being that person who can break an anvil with a feather duster :(

    You may have to degrease the stem and its collet then retighten.

    Never had any problems with mine either. Are you sure it's a problem with the die? I'd be curious to see if other brands would do the same.

    Mine (.223) was giving me fits with some range pickups with the crimped primer pockets.
    I pulled mine apart.
    Stuck the decapper piece in a drill and and sanded to a semi smooth uniform surface. (220 grit IIRC)
    Cleaned everything with brake cleaner.
    Reassembled with a generous, but not ridiculous torque.
    No more problem.

    Mine gave me fits today till I realized I had a few FN brass mixed in. Can't deprime FN brass with it.

    Since you didn't say "What kind of FN Brass", I would assume that its berdan primed. Kind of hard to punch out a new hole in the center of the brass.

    Getting to everybody else's problem, I use a lee universal deprimer only to insure that there is blockage in the primer pocket after I have sized/trimmed/swaged the brass. I use a Dillon size/decap die for all of my rifle cartridges. If the Crimp is really severe (and some are), the Dillon die will just punch a hole in the primer. Basically that brass gets recycled. But the Dillon die will decap 99.9% of all crimped primers.

    Yes berdan primed. I thought that is what all FN was.
