I swear this is not BS but years ago before the Atchafalaya Basin became "people flooded" {that's a damn shame too} there were 5 or 6 of us that used to hunt squirrels with .22 centerfires.............22-250 included (mine for one). The trick was with the cat squirrels was to find a feeding tree and let them come to you. During feeding times every 10 to 15 minutes one would be coming. Then the bigger trick was to hit him in the head. Take my word for it, there were not many misses of the head..............anyone who blew one up had to buy beer for the rest! That was a big incentive. Sad to say now there are too many folks around for that plus the state outlawed everything bigger than a ,22 rimfire for small game.
