To answer you original question about removing live primers. Just use your resize die and decaper just like you normally would. I do it all the time and have never had one go bang yet. Use common sense: wear safety glasses and just use smooth strokes and you won't have any problems. I sometimes in the past have prepped 100s of cases without labeling which primer they had. I recently switched over to using nothing but winchester primers to solve that problem. I've run 100s of cases thru my dillon 650 punching live primers out and pressing in winchester primers.
With that said, removing the decapping pin like most of the post above have said is great advice too. I just wanted to answer you exact question.
