I did something sort of similar at my local Walmart. They had the Federal Power Shok 7mm Rem Mag 150 gr SP for just $17.97 a box. I thought that was a great deal, so I kept buying a box or 2 every time I stopped by. The catch? I have never owned a rifle chambered for that cartridge! But, my farmer in Montana and his daughter both use the 7mm Mag on everything from coyotes to antelope to hogs to deer to elk, so I found a home for the 6 boxes I had impulsively purchased last year. And since he has put me up the past 2 deer seasons and got me on a pair of really nice whitetail bucks, I figured it was the least I could do.
