I'm looking for a 9mm recipe that would use small rifle primers. I have an excess supply and would like to use them up. Shooting 9mm is mainly for target competition and practice. Bullets would be for whatever would work with the recipe. Right now, I cast 124 gr semi wadcutters and use pistol powder, red dot or green dot.

You will find no published tested data for 9mm using rifle primers.

However, if you are only loading mid-level loads for range and practice, just use them instead of pistol primers.

Lots of people did during the last primer shortage a couple three years ago.

If your gun has enough firing pin power to set them off, there will be no safety issue from substituting them.

You would only run into problems if you were using a max pressure load to start with.

As always, start with the published start load and work up anytime you change components.
