i think you are asking how to remove the primers fom the cases, right? i was more than a little uncomfortable about removing live primers from a case at first. but thanks to the advice i got here, i tried it. i wore safety glasses, a sheild, 2 jackets and leather work gloves the first time. since then, i have removed quite a few, somtimes by mistake. if you have a universal depriming die, that would be the safest, just in case. that way, it would not be a tight seal on the case, and if a primer did detonate, the gases would have an escape route. i have never had a problem. just put them in the press like usual. but, still wear safety glasses. you should anytime you mess with any live primers! or, you could just load them one by one into the gun and drop the hammer. time consuming on 200 of them, but it works and is safe.
