    just wondering if any else has found some 45acp brass that was too long,:eek:
    i have loaded to many to count 45's most were for my old 1911.

    guess it is more forgiving then some new 45's out here now.

    i was checking a few rounds to make sure they fit and fed ok in my xd and i found 2 that kept the slid from closing.
    after checking everything twice i ck the oal of the brass and it was FEW thousands over max.:what:
    the 1911 closed on them but the xd did not.

    also found 4 that took small primers.:uhoh:

    just wondering

    Were you testing with finished rounds or just resized cases?

    If the test was done with finished rounds, I would retest with resized case only and see if the slide would close fully.

    If it does and not with finished round with a bullet, then I would adjust the taper crimp/OAL until it did.

    You could always trim the case, but I have not trimmed any semi-auto pistol case all the years I have reloaded them.

    it was finished rounds
    the oal was like 1.202 called for 1.200

    so far all the rest fit and the slid closes. i could see a ka-boom from this as the xd will fire a little out of battery
    (at-least it will if you hold the slid back a bit not with a loaded round in the chamber)

    i crimped them a bit more and still no go.

    that is when i measured the brass and found it to be longer then the max in the books.

    i also have never trimmed any thing less then a 50ae

    i only found 2 but there might be a few more in that lot.

    just something else to dbl ck now , most of my 45acp brass shrinks a bit .

    i use to be able to use my 1911 as a gauge if it fit in it they fit all the rest ,,,, not true now i guess.

    i ran then through a lee loaded case carbide crimp also, so it should have fixed any bullet problem, so far that die has done a good job,

    i have had some rounds fit a Dillon case gauge fine but not chamber, then i would run them in the carbide gauge and they loaded like there suppose too

    Were they the same head stamp?

    If only one head stamp is long, perhaps it is due to manufacturing defect and lot?

    The XD has a short leade, and you may have to adjust your seating depth so the bullet doesn't contact the rifling.

    Small pistol primers were brought about by the adoption of Diazoninitrophenol (DDNP)priming compound to replace the old lead styphnate priming compound. The higher brisance of the DDNP compound required some changes in primers, and using small primers was one of the changes.

    Hope this helps.
