AIM has Russian 5.45X39 in stock right now. This is the nice WASP ammo, with the steel core and air pocket at the tip to make it tumble. $149.99 for a 1080 round tin. 2 tins in a crate. Just ordered 4 tins (2 crates) myself. Great deal if you have an AK74 or 5.45X39 AR15 to feed. I thought about driving to pick it up, as they are just south of Dayton, OH, but the shipping charges were the same as what sales tax would be, plus I don't have to waste 5 hours of my life.
