no booms.....just was ruunin' a few 380's in single stage and ran the decap pin in my finger
I also have done this. Started neck sizing my 10mm and had the decaping pin protruding further from the sizing ring than standard. I got in a grove and got going to fast when I had one that didn't get on the shell holder far enough. When I went to push it the rest of the way in my other hand went ahead and pushed it up while my index finger was in the way. I actually thought the case had cut into my finger at first. It didn't hurt right a way either, but dang it was sure sore for a couple weeks while the scar channel worked it way to the outer layer of skin. Sure hope I never do that again.
