Marc,
Many thanks for the heads-up. I spent so many years flying with the ammo in a separate case (I even have a dedicated ammo case!) that I never realized the rule had changed. Talk about being unaware of your environment!
As for locks, my trouble is that I live in Fort Worth these days and it's a couple of legs to a lot of shooting destinations, like Africa, BA or much of continental Europe. (Still one leg to London.) This gives our friends yet another shot at examining my cases and they sometimes take it. I wish someone would make a TSA lock in a decent grade, but the bad guys probably knew the codes the day they were set, so there may not be a lot in it.
