RCBS swaging. I recommend contacting RCBS to find out if you have an obsolete rod (made out of softer metal) or the upgraded version made of hardened stainless steel. My swager was new from MidwayUSA, but I guess they have some inventory on the shelves. RCBS sent me a free replacement, and I had it within a week of contacting them and they paid the shipping - excellent customer service.
I went for a swager because primer pockets loosen up over time and it seems even faster with my Federal brass. If that is the area that seems to fail first or more frequently (primers wont seat, just fall out) it seemed more logical keep as much metal on the pocket as possible, and force it open rather than cutting/removing metal.
Just my reasoning...
