Well gentlemen, I did it again. Something I've not done since my very first day of reloading .223. I got my decapping pin stuck in a .357 SIG case. I just dived into this caliber and have been excited about it for a while now. Well, dies came today as well as my brass, so I figured I'd size them, and set them aside for priming/neck sizing/etc. when my bullets arrive. I have read countless times on here of people sizing and decapping using their .40 dies, to avoid lubing the case, followed by running them thru the 4-die .357 set. Well, I decided to do the same. The very first case felt a little "stiff" on the down stroke, and the upstroke as well... I then realized that's the all too familiar feeling of me slowly pulling the decapping pin out of my die. It's jammed in there good, bottom of it is flush with the top of the primer cup. What gives??? Are the Sig's flash holes smaller? That seems odd to me. I'm pissed off, now dead in the water for .40/10mm and too annoyed to do anything further with the SIG like lube/size/decap with the specific .357 dies I bought. For what it's worth, it was a Speer case from a mixed headstamp bag of 500 once fired cases.
