Looks like Cheaper Than Dirt has Winchester M22 (.22lr 40gr.) in 2000-round cases for $77.00! To those of you who have tried them: what do you think? Winchester claims they are "AR-format" specific, and designed for improved cycling and accuracy. Am I going out on a limb by buying 2000 of these boogers for my Colt/Umarex M4? Of course, I'll have to wait till I need to order some more "stuff" so I can offset the ridiculous UPS shipping on ammo!
