Question about reloads in a P7

[P7_Id10T]

I just set up my reloader for 9mm and cranked out ~75 rounds.
They all look good, dial in at 1.134".
Sampling on the scale for powder all come in as light loads (4.1 grains of Accurate #2, 124gr JRN Hornady), which I'm happy with for plinking.

However I found ~20 that are crimped, but I can rotate the bullet in the shell. Can't pull or push it in, but just rotate.

Apparently I didn't have my crimper set properly.

I planned on shooting them, but will these affect my action or pose a danger?

Don't shoot those. Run them all through your crimp die before shooting. Improperly crimp rounds can set back and potentially drive the pressure way up.

Thanks Scooter.
I already figured I'd toss them or pull and reuse just the cases.
