You should really give Starlight Cases a good look. I've had one since 2001 and it has traveled with me several times on planes and landed in pouring rain here in MS, Colorado, Oregon, Louisiana and the rifles/shotguns and pistol inside has never had a drop of water. It will take a good beating without issues. The last time I flew into Jackson, it sat outside for 20+ minutes in a downpour and it was soaked when I got it. When I got home the case had to be wiped down but the inside rifle/shotgun and pistol were all dry without any hint of moisture-and they're US made.
