    I’d say I only have 5000 or less rounds produced using this seater punch over the last 2-3 months, and it appears to already have a wear issue that is transferring dimples to the primer upon seating. I am not using excessive pressure; any less pressure and I will not properly seat the primer. Anyone else experience this issue? I was also going to reach out to Hornady warranty, as this is a $15 part. The large primer punch looks just fine, and I think I probably have produced more large primer rounds than small on this press. Thanks in advance for advice.

    I have lost count of how many small and large primers my LNL has loaded but it’s in the tens of thousands. The only issue I’ve had with primer punches is one broke at the threads. Don’t know if it was a flawed punch or my fault. Contact Hornady with pictures and they will send you a new one.

    That's just a small machining mark that did not get cleaned up. This can also happen when some debree ends up on the punch. I would just take some 600 grip sand paper and smooth it off. There is a small clip on the other side holding it together, with a small spring.

    Can't say I've ever truly 'worn' a punch down in my LNL AP, but the frame will certainly wear away directly underneath the punch.
    (I JB welded a fender washer over it.)

    True. I’ve taken notice of that crater that’s growing over time. I assumed sooner or later, it would impact the primer seating depth.

    I have worn a couple out but it usually takes 40 to 50,000 rounds.

    Just call Hornady, they'll send you into one for free. And while you've got them on the phone have them send you a primer slide too.

    I'm obviously either cheaper or less handy than you. I took some painter's tape and taped a nickle over the indention

    Put the ram up and you can unscrew the primer assy, primer seating plug assy.jpg this thing. You can take it out with a 7/16" wrench. I had one that was doing that, I worked it over on a wet stone and took the dimple off of it.
    The dimple on mine was there from when it was new and is from the person that machined it off, didn't have his tool bit in the center of the work piece so when it got to the center of the punch it didn't clean it off and left a small point.
    Call Hornady and get a new one coming from them, then take the old one and stone the point off of it. If you mess it up you aren't out anything, if you don't mess it up you have a spare.
    But it shouldn't have been like that to start with.

    As far as the dimple goes in the frame, I have over 75K ran through my press, at least, and have had no problem with my primer assy not seating my primers deep enough. It will eventually get to where it is a problem but the fix is easy enough.

    Hornady will send you a new one. I’m really surprised there’s a pimple on the surface of that seater. Looks like the CNC process didn’t quite complete, and, I would think that was there initially, it didn’t grow there. A file would smooth it off too. Good luck.

    Thanks, all. They did send out a replacement already. As others mentioned, I’ll disassemble and sand it flush and keep it as a spare.
