FYI Ohio Rapid fire has 5.45x39 ammo at $299.95 for 2160 rounds case in wooden crates.
I appologize for the duplicate post snafu.
Sportsman's Guide has 5.45x39 ammo for $144.97 per 1000 rounds. That works out to .1449 per round vs Ohio Rapid Fire's .1388 per round.
Sportsman's Guide is also selling Russian Military Tula ammo for $284.97 per 2160 case (that's .1319 per round) so they are just ahead of Ohio at this point in time.
AIM has 1080 rounds for $169 or .15648 per round.
J&G has Russian Military 1080 round case for $162 or .1500 per round.
I hope it drops some more.
