Back in the spring when I was somewhat low on .22LR, I found Federal in the 525 format (which my firearm really likes). I crunched it out to about $0.06/round after all taxes, shipping, etc, and thought that was a little on the steep side back then when I was paying around $0.04 up to that point. I bought I think it was 15 or 20 packs back then, and I'm glad I did. It sold out a few weeks later, and hasn't been back since at that retailer, and everything comparable is well over the $0.06/round I paid back in the spring. It's not a tonne of .22LR, but it'll keep me plinking for at least a few years on that one order alone.
