Yeah the wife got pissed when she found a loose round in the washer.     Oops mah bad.  To lessen your headaches, I wouldn’t recommend using range bags as carry-ons. I got stopped at TSA at HNL because I used my range bag.  It would seem from everyone’s responses so far testing seems to be inconsistent.

It still fired also.  It was an Armscor 9mm.  Which answered the question I had about rounds being submerged in water (flood, hurricane, etc..) Will they still fire?  I shot it the next day.  Left it in a cup of water over night.  No sealant on it or anything.

    I once used my backpack to carry fireworks to aunty's  in Waipahu for a family 4th of July a year or 2 after 9/11
A week later used the pack on a family trip to BI.

      Should of seen the hub-bub when the bells and whistles went off after I was "randomly " chosen for my bag to go thru a sniffer.
I, wife and little kiddies must have been stopped and inspected at least 10 times including just before getting on the plane where you show your boarding pass.
Funny thing was is that when we got to BI, Rockette found her Leatherman (you know, the one with the 3" blade  ) in her purse which was inspected all those times.   
Go TSA
