Has anyone tried this stuff? Saw it at Gander recently ($55 per 1000 round box) I've read its available elsewhere, like walmart for $45. Still not as cheap as 555 for $20. Supposedly this is winchesters response to CCI tactical? Slightly more per round but supposedly feeds better.. I know that CCI proved that it was more reliable, but I'm not too sure about the winchester.

yeah, there's already a thread for it. try searching winchester m-22
