What the Sam Hill is N.T???

    I was loading up some 9's this morning on lee progressive, and had a couple of these.


    After making sure the press was ok, I looked a little closer, and determined the only cases this was happening to were cases with an "N.T." mark.

    Upon closer inspection, I see there is a ring on the inside of the primer pocket, making it to small for the primer.



    What the heck is this nonsense? Of course I would never use the word heck when having loading problems.:p

    I have no clue where these cases came from. I'm guessing someone gave them to me.

    Non toxic.

    I have had super accuracy success with the win NT cases....they weren't crimped though...

    Federal Non-Toxic.

    The primers are crimped in just like military brass.

    The lead-free priming compound is more powerful then normal primers and the primer crimp is used to keep them in the pockets.

    You will have to ream or swage the crimp out to reload them.

    NT stands for new technology. Winchester's lead free primers. What you are dealing with is a crimped in primer. That "ring" will need to be reamed or swaged to remove.

    NT are a problem for those of us who reload 45 ACP also, as they use small primers instead of large.

    Oops. I stand corrected. Non-toxic. :)

    That pocket is crimped. I have had a few of them in my 9mm box. They will prime if you use a hand primer. That what I do with all my 223 and most of my crimped 9mm.

    As far at NT I have no clue, but there are good to shoot.

    Get a swager and take care of the crimp and go back to reloading.

    I guess I've never played with military stuff.

    Into the brass recycle box they go!!!

    Thanks RC.

    Yup...those New Technology cases will get your press all constipated in a hurry! I keep an empty container on the bench to toss them into just in case someday I run so low on 9mm brass that I actually bother to ream the crimp out!

    Fortunately, they have a copper colored primer, making them easy to spot, and pick out.

    Most of my 9mm bras is crimped. I swage all new to me 9mm brass.

    segregate them out with any nato brass and handle/use them seperately....

    as noted.... they are often crimped

    Whenever I prep sized "pickup" brass I check headstamps just to see if there's anything unusual or unusable in the mix, and as I go I ream anything that's crimped. I use an RCBS prep center to clean primer pockets (yeah, I know most people don't bother) and chamfer the case mouths a bit, and it takes very little extra time to ream out crimps while I'm at it. There's another tool head spinning just for that purpose. Once and done.

    Dang, this thread was hard to find again. *whew*

    I shot these pics of my Federal LE 9mm frangible brass (this stuff http://www.aimsurplus.com/product.aspx?item=AFED9F98 ) and Remington UMC "LeadLess" 9mm brass... and I can't see any crimp FYI. I've reloaded a bunch and have never had problems. So not all "NT" or non-toxic primed brass is problematic.

    Not that anyone cares, but I took the time to snap and upload the pics, so danged if I'm going to let them go to waste! :D

    I use them and just take care of the crimped pocket when I, "also", clean the pockets. I know, us primer pocket cleaners are a dying breed. Oh well, it helps me sleep better at night knowing they are clean. Actually, on a more serious note, I feel like I get a more positive primer seat when they are free of any carbon deposits?

    Before they started crimping them I had some Federal eat up my breach face. Tarus replaced the slide for me.

    I've shot a billion of these with zero problems FWIW.

    Well... I have come across that headstamp in my range pickups. Had no idea they were crimped. Guess when I get a round tuit and ream my NATO brass I'll do those as well.

    they aren't... not all of them, anyway. see my pics above. :)

    Also, depending on your priming setup, you may not have any trouble even on the NT brass that does have the little ring or lip around the primer entrance. I wouldn't call it a true crip, at least in the OP's case.

    My Lee safety prime on the LCT will prime them without issue, and even handles most winchester nato brass (which IS crimped) without issue. I end up mangling maybe one out of 10 primers in those, so I generally just recycle the few nato brass I come across.

    Don't toss them! Get a regular old countersink and cut that ring out of the pocket. Millions of military cases are reloaded after this simple process. I hold the brass in my left hand, countersink in my right. Insert and twist a couple times (takes mebbe 2 seconds), and now you're ready to stuff a new primer in the pocket...
