    The seater is the correct size. Any trouble come about from the brass i got from some Winchester ranger ammo. It was the 124gr FMJ 9mm NATO boxes. Do some manufacturers crimp the primer or something?

    They do not go in off center. It seems to be more of a matter of skipping cleaning the primer pocket. Perhaps it stops on some crude and the other side goes a little lower.

    After proof reading the previous thread it seems it may be a good idea. To clean my primer pockets, or maybe not use the Winchester brass.

    The one has an odd headstamp. WCC 10 and a circle. Different coding than any other Winchester I have come across.

    I'm pretty sure the Nato primers are crimped in which unless the crimp is removed prior to seating a primer,the primer either won't seat,or you end up cruching the primer trying to seat it,I have had some cases that when it feels like the primer doesn't wanta seat using normal pressure I remove the case and examine it,if it looks like a crimped pocket I toss it,I have more brass than I will reload in my lifetime,but I may need it someday

    Then that must be it. A lot of it gives some resistance and leaves that piece of brass behind. Probably excess brass from crimp.

    Guess I should just settle on tossing some of it.

    +1 I've had a few of these (like maybe a couple hundred out of thousands of 9mmP I've loaded), shot them all, no problem.

    This has been my experience also. Love the Dillon

    Yes, NATO primers are crimped in.

    Agreed, I have never had one fail to fire. That said I use those rounds for range use and plinking only. Never for my everyday carry or hunting situations.

    I was looking up removing crimps from 9mm brass and seeing people having to remove it from the same headstamped brass. Looks like I need a swager.
