I got a new batch of once fired 50bmg cases in the other day and I sorted through them and they were all winchester cases except for one FN case. The FN case is boxer primed but the firing pin hole is just a tad bit smaller than normal and I didn't notice it at first and ended up breaking my decapping pin. So just a warning to anyone who comes across one of these cases to either toss the case or go slow if you think your decapping pin will go through. I bought these cases from HiTech and I'm using Lee dies.
