I need to transport a Winchester shotgun back on AA with me Monday. I've never done it before, and looked up the requirements:
- must be unloaded
(check!)
- must be in locked, hard-sided rifle case
(uncheck...)

So, anyone know where--not specifically in my location, but rather the type of store I need to check (WalMart, KMart, gun shop, etc.)--I can purchase something that the TSA and and airlines will allow me to check, as well as roughly how much I can expect to spend?
