Leo-
I know in 2004 I was flying with ammo in the gun case. It could have been 2003 though, but definitely NOT in 2002. Anyway, it has been that way for a few years. Before that I would have to keep ammo in my suitcase, per the regs.
Regarding the regs, no, in the past you could not fly with ammo in your gun case. I fly a lot with guns, in several countries on several continents, and it was consistent. Now eveyrwhere I go they tell you to just throw it in the gun case.
Regarding locks: I just use Master locks I bought at WalMart where I got 4 locks keyed the same. I always fly with 2 locked on the case and just hang around the ticket counter until TSA calls me to open the case. They always scan it to see if they will have to open it, but every time I fly they wind up opening the case. Does not really matter to me. After the inspection the case is locked again and I go through security.
