I am looking to stockpile some "just in case" ammo for my Bushmaster. It does not have to be a specific defense load or a target load. A plinker will do. Does anyone have any good internet finds on bulk ammo? What's the deal with the Wolf ammo? I have hear some negative press on the Wolf including one range that will not allow you to shoot it. Also, any strong opinions on using 556 versus 223 in a late model Bushmaster?
