since when can't you pack ammo in your rifle case?
as long as the rifles unloaded...?
I've always removed the bolt too, as the case closes more easily that way...
Plan on having the guncase opened/inspected before you check it in...
Probably just give your airline a call, or check online what they say...
Might be an extra charge due to weight...2 rifles in a double rifle case, plus ammo, isn't light...
