Ok, so here is the whole story. After I lowered the bar on my RL550 (I was lucky enough to inherit it from an uncle who no longer was into reloading), I got a case that I thought was soaked in lube stuck. I have the dillon dies (.308). So I tried following the instructions that came with the dies on removing a stuck case. I screwed the depriming assembly as far down as I could and tried to remove the case with pliers (per directions). Enter blisters one and two from pliers slipping.
Next, I figured I would use my RCBS stuck case remover. Unfortunately, I would have to drill down the decapping pin in the die in order to be able to pull (oh well, the dies came with a replacement). So I drilled away, tapped, and tried to pull. After fiddling, finally got the case out. By this time, I had also stripped a little off the edges of the depriming assembly trying to get it down more.
Enter vice grip. So I thought tightening the vice grip down on the top of the depriming assembly and going from there would be able to get me a usable die. So, in the process of tightening it down, my and slipped a little (from the lube I was using) and a whole bunch of pressure went into bending my thumb back to a snap.
I have been reloading for two years, but that doesn't matter when you are having a stupid day.
