Pelican cases are also great protection (i use them for ground travel with other gear) - i do have a two gun Americase

but the TUFFPAK does not scream gun - the only attention i got in an airport in Scotland was from golfers asking me where I was playing

it's round on top so heavy things cannot be stacked on top

you put your gun in your case inside - pad it with your hunting clothes or what ever and nothing moves

there are several good options - just saying the tuff pak worked great for me - I got the one i used from a guy who had used it for multiple trips to Africa and swore by them
