Issues at DIA with "Assault Weapons" and/or magazines >10/15 rounds?

[Oscar77]

TSA is extremely consistent at being inconsistent. I have heard stories that differ from airport to airport. You won't go wrong with ammo in a box separate from the mag.

You aren't usually dealing with TSA, it's the airline ticket agent that you work with.

The only time I deal with TSA (sortta) is at DIA.
Once you declare your firearm, the Agent has you escorted to a room where TSA is "working", they get the keys to the case from you, xray and inspect it and once done return the keys to you and your bag goes on its way.
All the other airports (maybe 7 or so), the Agent asks you to wait 5-10 minutes there around the counter incase they need the keys (never been asked).

The ammo thing is an Airline request, along with the usual: Unloaded etc.

The only time a Ticket Agent was rude, seemed more about the slowing of the line to deal with the "card" and not so much that I had a rifle.

PS: Even when I've flown into California, nobody has asked/cared about what magazines I had.
Again, in all the times I've flown, its the ticket agent that you are dealing with, just get the card filled out, put in the case and locked....... done.

Be cool and respectful, save the 2A rants for someone else.
The Agent just wants the bags on the plane.
