If it is anything like the first (or like any other video game) you can only scavenge for ammo from weapons of the same make laying on the ground.
If properly stored in cool, dry conditions, modern ammo has a very long shelf life. We do not know how long, since modern day ammo dates to about WW II (1940s). I have recently shot WW II ammunition, and it works fine.
As a general rule, NO, NO, NO!!!!
No
Im not for sure about the glitch but if u need more ammo just get Scavenger and keep picking up ammo and if you get Scavenger Pro you get Extra MAgs.
Any modern ammo will do, except for +P.
I don't think there is any +P ammo made for the 32 auto ????????
If it's a modern .30-06 rifle, yes.
