 Someone buying one box of ammunition, especially someone who is a member of a gun club, will not set off any alarms. Most people will buy two to four boxes when they go to a shooting range. Yeah, that whole thing, people just don't understand. Confusing rounds, I think, for clips, maybe. That's the only thing I can think of because that was the first thing when I started seeing it. Oh, my gosh, why didn't red flags start going off when this guy purchased 50 rounds?
