If you were given a rifle and a side arm and then the supply line person said how much ammo do you want? You say, "All I can get". Same applies away from the battlefield at home. How much do you need-want and how much can you afford. Never underestimate your ammo need. It may be a nice security blanket down the road when you cant find an ammo dealer anymore. Rifle and no Ammo equals a dead weapon. Ammunition can be a source of currency in barter and trade times. Example I will give you 20 rounds for a dozen eggs. Be smart be prepared.
