Ask Sportsman's Warehouse when they next expect some in (they're in Twin Falls). Also check with Quick Response Firearms. He's in Twin Falls also. Something else you might consider is to check Cabelas online. I'm in CA and recently checked Bass Pro (now owns Cabelas) for non-lead turkey ammo. I was able to order some into a nearby store where I could pick it up after being backgrounded (Communist CA), Grrr.). If Cabelas has the ammo, you should be able to get it mailed to your residence in Idaho. Failing that, start checking out SLC.
