I haven't seen this before but it sure causes issues that my range brass included someone's Berdan primed 5.56. Cruising along with my Dillon 1100 and come to a screeching halt with a bent decapping pin, twice.... I think I have the feel for it now so I've pulled out several without a bent pin. Had to slow down a lot.
Thought I'd post because I'd never seen it before. I had to cut the case down so I could verify, here are pictures.
