So I understand this may qualify as a dumb question for some of you, but I am new so don't be too harsh. After searching this forum for some time, I've seen a lot of people recommending common calibers so ammo can be found in country if the ammo luggage is lost. But several airlines allow shipping of ammo and guns in the same case. Why not just pack them together and not worry about losing the ammo? Is there something obvious I'm missing or does anyone have experience where it was a negative to check ammo and firearms in the same bag?
