In Tommy Blackburn's "Jolly Rogers" book about VF-17 they do this too. They have to move from one island strip to another, and all their transports were full, and they figured if they sent their stash of beer on a ship, they would never see it again.
So, they took all the ammo out of one fifty cal from each wing of each of their Hogs, and used the empty ammo cans to load 2 cases of beer per fighter.
Just before landing, they went up to 30k for 10 minutes, landed, and handed their delighted ground crews an ice cold beer each.
Would have made them immensely popular with the ground staff at the new strip I would reckon
