Bruce,
.22 RF should bust loose up your way shortly. The Walmart in Sierra Vista has a ton of it right now. Maybe our Cochise County hoarders now finally have all they desire. Prior to the last 6 months or so, I have not been able to buy any .22 RF there. Occasionally found some at CalRanch store. Didn't pay attention to centerfire since my duty ammo is provided and I shoot handloads in all of my personal weapons.
