Went to CTD today and aside from them being out of preban 20 and 30 rd steel mags, it went off fine. I bought 3 boxes of Korean 3006. Once I got home I took the boxes, dumped them out, and inspected EACH round. I found 8 that had nicks/marks on the lip. A few looked like they had writing, a few others had little thin lines going up the lip. I assumed they were cracks and quarantined them for further analysis. BTW, they were headstamped PS 74 and I think could have been either PS-2-104 or PS-2-134 lot numbers. No need to avoid these lot numbers, just inspect your rounds. I only found 8 out of 60.
