I recently bought a Hornady Hand Priming Tool. Liked the idea of a single tray for both large and small primers as I always misplace the one I'm not using. I just tape the punch that's not in use to the bottom of the tray so it doesn't "wander off and hide on me too".
The tool itself is great. Easy to use and with the "shutoff" feature on the tray cover I don't have any primers spilling out when I put it away with a few primers left in it.
Unfortunately---------
When I started using it, I started having more FTF's than I ever had in 40 years of loading, using some of the most questionable primers one could imagine.
Hornady for some reason they won't reveal has put a rather large radius on the edge of the seating face of the punch. This focuses all the seating force to the center of the primer face and if a primer is a little "stiff" going into the primer pocket it "dishes" the primer face. EVERY SINGLE MISFIRE that I've experienced whille using this tool has the distinctive edge marking of the dished primer face.
Can anyone explain to me the value of the radius they insist on applying?
Here's a couple pictures of both the "punch" and a couple of cases I primed using both a BR-2 primer and a Wolf Primer.
Just wondering if anyone could clue me in because Hornady has been no help.
I've been looking carefully at how the punch is adjusted and will just be using this tool as a Hobby Project, making an adjustable depth priming tool with a "Flat Topped Punch".
Yeah, I know, I should have just bought a Century 21, right?
