we used to call it snake shot. I dont recall ever using 22 snake shot. But I had some for my Ruger .357 flattop. It was great for snakes and semi ok for grouse. I'd put the distance more like 4 or 5 feet. I shot a grouse once at about 10 - 12 feet, cleaned it and only found 1 pellet. It was stuck in the breast, didnt even pentrate to a vital area. The sound of the gun going off probably killed it.
