I bought a bag of 200 357 mag brass at a local gun show. When I started to re-size them, I noticed that one had a live primer. That really got my attention, and I found that 62 of the 200 had live primers. The brass has NOT been re-sized, and I suppose that whoever dumped them must have decapped and re-primed and then realized that he/she hadn't run them through the sizing die.
Now what do I do? I assume I can take the decapping pin out of my Lyman TC die and size them, but I don't know if the primers are sp or spm. I hate to "pop" them all off if I don't have to.
