Cci .22lr
I know of several stores that occasionally have CCI and other brands of 22 lr.
One of my most reliable is Bi Mart which has a number of stores in both WA and OR. You're usually limited to 1 or 2 100rd cartons, but they only charge the familiar $6.75/100 for CCI mini-mags. I have one pistol that thrives on these, and buy them whenever I can. I also picked up some at Wal-Mart and Cabelas on occasion; but their prices have always been higher. Wally world was 5.98 for 50 rds of sub-sonic CCI. I always try to buy some before I go shooting. Sometimes it takes two or three purchases before I have enough for a shooting session. I have a backorder with Midway for 1000 rds of CCI and some Winchester. It's been on backorder for a month now however.
Good luck! :grin:
