Flying to South Africa in three weeks, I currently own a pelican V800 double rifle case. When I fly to Maine last year to sea duck hunt The airline said my case was to large to put in the machine and I had to leave it unlocked for a manual search. not wanting to do that on this trip was that a fluke and I should have argued through it or do I need to buy a smaller case and if so what’s the best size for a rifle and a shotgun?
