In a rifle, of those posted, I'd only shoot #1.
Now at MSC, the range is used by a number of LE, private security, and commercial contractors too. While MSC is required to police all their brass, nobody else is (I'm not complaining about free brass!).
There are quite often live rounds left in the dirt, from them running drills. Much of it is very new if it is found not long after being dropped (I'm not complaining about free ammo!).
Some though gets dropped and has dirt kicked over it and it disappears for a period of time. With pistol ammo only I've tried some in various pistols just to see if it would fire. It all has! I've tried out 9x19mm, .45acp, and .22LR that looks like it was dropped during WWII. Living in the dirt keeps most of the corrosion to a minimum but it looks old...very, very old.
We found a bunch after the Appleseed this past weekend. If I remember, I'll take photos and post a range report. Even found a varnish-coated steel-cased .308 that I won't shoot out of my rifle, even though it is new.
