Meijers here has had tons of Remington 30-06, .243 and maybe 30-30 (not to sure on that last one) sitting on the shelf. I picked up 10 boxes of PMC 55gr .223, and the other 10 boxes were gone by the next day ($11 for 20 rounds). The clerk said they did get a couple of bricks of .22LR in but they were gone within hours. You can get .223/5.56 off gunbroker sometimes for $.75-90/round.
I bought a 1000 rounds of 223 for $699.00 a couple weeks ago, but I just happened to be there when it came in, all gone in a few minutes. As for 22LR I have purchased several bricks at a local store, but when it comes in it doesn’t last 5 minutes and that is with a limit imposed.
Get in line early before the store opens then run as fast as you can to ammo department elbow in to get you allotment, then hustle to checkout where you put up with the abuse of late shoppers who call you a racist horder. :)
