Erich, bang on about the weapons, it is NEVER a good idea to fire ANY weapon that is not in top condition. The same goes for ammunition, it degrades over time and try to remember that if you have a missfire that round suddenly becomes VERY dangerous, there is a reason for the complicated missfire drills the army has.

I also agree with what the others are saying about the ammunition, you are literally burning money, well, burning a large amount as a propellant to throw more money across a field...
