re: 5.56 $ cost philosophy vs Russian rounds

I've got hundreds of clean, once-fired Lake City brass in 5.56 and 7.62 that I'm going to start reloading once primers and powder are available at prices I'm willing to pay. Even up here in PA, 150rd bricks of Federal green tip are fairly common and are just below $.50/rd after tax. I grabbed a few boxes of Summit and LC 5.56mm before the insanity so I'm in no hurry to buy ammo.
