I'm looking at a Wards bolt action rifle in 308. It's the old Mossberg 800 model. Can I safely shoot any milsurp ammo in it? I would probably avoid the steel case stuff, but how about brass case? I'm just showing my cheap side(which is my best side, by the way), and looking for cheap plinking ammo. I know this has come up before, but I was wondering if others have tried this and what they thought.
