I have 60 empty 308 paper ammo boxes with the plastic inserts in them. I moved some ammo around and now have these empty boxes. I'm sure they can be used for other calibers, but they had 308 in them. They are the regular 20 round boxes. Nothing special, except that they are all in great like new shape and that they're FREE. Bad news is that you have to take them all. I'd prefer not to split them up. I'm in Hillsboro off TV & 234th. Come and get 'em. My cell is 818-406-6605. My email is firstname.lastname@example.org Call, text, PM, or email me.
