Hi all.

I have just started loading primers into my first 10 brass casings using the Lyman handheld primer device. They all seem to fall within the 0.003 and 0.005” as per the manuals, however each primer has a small round indentation afterwards. Is this normal? I’m guessing it must be coming from the tool but not sure if it’s ok.

Priming rod in upside down?

how hard are you having to force them in?

I have an E-Zee loader, and they should seat with minimal pressure, not having it feel like a hand excerciser

I don't believe that I've seen that mark on any of my primers during 10 years of reloading. Bearing in mind it appears to be very consistent, it shouldn't be that difficult to establish what's causing it. An indentation like that on a primer (other than when I pull the trigger) would definitely concern me.

Dirt or grain of powder on the priming rod?

I managed to get a similar mark when I tried to prime with no primer and the rod stuck in the bottom of the case, I had to knock it out of the case and it put a small dent with raised edges in the priming rod.
I filed the top flat and all has been good since.

Is the indentation a result of the priming tool or is the mark already there on the primers prior to being inserted in the case? I ask this because on occasion some brands of primers bear very small factory identification marks but these will usually be seen only on factory ammunition only e.g. "n" on Norma ammunition.


I would be slightly concerned if the priming tool is putting this indentation in the primer cup and would be contacting the tool manufacturer to query this. Possibly a small nib left on the end of the priming rod when it was turned off?
I wouldn't however be overly concerned if the priming tool has made this indentation and the primer has seated properly without igniting. I doubt very much if the indentation has affected the integrity of the primer cup.

As Dromia said check the priming rod, one end is flat and the other convex. I did the same in mine.
Flat end needs to be pushing the primers in.

It seems like a sealed unit to me that mostly made of when bought. I could see the part that clearly wasn’t machine completely flat and just filed it down slightly. Works a lot better now. Still not 100% but ten times better than it was. Thanks all.
