I went looking for 7mm-08 ammo for a friend and had great difficulty finding it, especially at WalMart, Dicks, and a few other places. That was a couple of years ago and though it's easier to find now, prices are ridiculous.
The other thing I've noticed at the super stores is the poor selection of bullet weights and shotshell shot numbers for the game in this region. Guess that's what happens when corporate buyers try to pick the narrowest selection of products merely to maximize profits nationally. Yuck!
