Guns, Dogs and Blades QnA

I deer hunt with a .357 rem max I have only been able to find brass to load my own ammo never have found factory loaded ammo
Invariably every time I ask about that caliber for our Island buddy whoever I ask looks at me like I have a third eye. They then simply shrug and tell me ya gotta load your own. It is not your everyday pick up a box off the shelf ammo.
