K&M primer tool

[grovey]

I use K&M primer tool, it's the model with the gauge . These use Lee shellholders, and when I seat primers in my 6ppc cases it takes a little bite off the edge of the primers. I have to turn the tool upside down and tap it most times to expel the small qtr moon shaped sliver. I do this over a clean piece of paper to make the slivers easy to see and depose of. Lil bastids are sharp!

I've primed a lot of different brass with the 3 most common boltfaces and other than some super tight primer pockets in new lapua 22/250 cases I haven't had a problem. Has anyone else experienced this with this tool? The ppc brass is the only thing I use this shellholder on, so I don't have anything to compare it too. To me... my shellholder has be the cause of this???

Try another shellholder is my only suggestion

I too have the K&M primer tool, except with out the gauge. But I've not had the issue with mine like you are having. It's been the best, strongest, most adjustable priming tool that I've owned. Sorry that I couldn't help you solve your issue with yours. Good Luck

I had a similar issue with a lee shell holder in the lee hand priming tool, changed shell holder and fixed the problem. I put it down to machining was a little less or more on the faulty one.

I'll grab another shellholder next time I order. Thanks to all that replied.

They'd be Federals, I'm guessing.

Actually, no. I've tried CCI 400, br4's and the Rem 7 1/2's. I can't remember off the top of my head which one, but one of the aforementioned CCI's only did it 50-75% of the time. I just seated the last of my 7 1/2's and every one got a bite taken out. Although I blame the tight seating primers in the new 22/250 I mentioned on the fact that they were 210m's
