Not saying it couldn't happen, but it would be highly unlikely. My best guess would be he dropped the box of ammo, projectile side down, causing one or more bullets to be shoved further down into the cartridge than it should have been. Kind of like what SAFriday was talking about in his thread the other day. Only a guess on my part though...
Possible, but pretty unlikely. Most revolver cartridges (especially magnum level rounds) have a pretty heavy roll crimp and a cannelure on the bullet to prevent bullet movement under recoil. Mostly this it intended to prevent the bullet from moving forward and locking the cylinder, but it also serves to prevent rearward movement. If I had to guess, I'd say squib followed by full power round, but you'd normally see a bulged barrel, unless the first bullet stopped right after the forcing cone.
