When I was in Phoenix for the Cactus Classic in November I had to go to both Bass Pro and Sportsmans, in the Glendale area sorta, to get enough 12 gauge premium shells to shoot the tournament. I pretty much cleaned them out and wound up with a mix of STS, AA, and HOA shells in both 1 and 1 1/8 oz loads, so there wasn't much at those two stores at that time. I imagine there are other stores in the general Phoenix area that have a bigger supply, I just don't know who they are or where they are located. I am flying down for the Arizona State so I need to measure how many shells I purchase as I can't take more than a couple boxes home. I am not very knowledgeable about the new Phoenix. I used to spend time in the old Phoenix in the late 70's and early 80's, it is a whole lot different now. I do like how they have no regard for the speed limit.
