I had an interesting experience flying today. I had to travel for work, and I bought some ammo (slugs) before heading to the airport for my flight home. I've done this many times and declare my ammo at check-in. I'll usually get a question about factory packaging to which I give the affirmative answer. This time, they specially tagged my bag saying that ammo cannot go on some of the planes in their fleet...specifically the Airbus A321. The plane typically servicing my route is the 717, but the A321 is sometimes pressed into service, thus my ammo had to be tagged for that possibility.

Any commercial pilots on here that can shed light on the "why's" specific to the A321?
