By a few boxes, do you mean boxes of 1,000 rounds or like 100? Hehe
While I was getting my rifle worked on I think I saw a bunch in patriot. They actually had a lot of .223, 9mm, and others. I need to go in tomorrow it pick it up if you want me to check on what they have and how much for you.
Tony, if I were closer I could help you out. Are you willing to order online? There's .22 LR ammo online, you just have to dig. Bass Pro has 50ct boxes of 38 grain HP Federal American Eagle in stock for $2.19. It'd work out to $21.90 for 500 rounds.
