Really hoping someone here can help me out. I had cleaned 100 rds of .223 brass tonight. When I ran them through the size/de-primer station this is what they came out looking like (look at the top of the neck). I thought maybe my die was dirty so I cleaned it, then ran another piece of brass through it but got the same result. Can anyone tell me why they are looking like this and if they are still safe to use. This lot of brass is once fired PMC. The last batch of brass that I did look fine. Sorry this picture is so large.
