The best head for squirrels or rabbits is either a muzzy or thunderhead with the blades removed. If your gonna hunt some big fox squirrels leave the blunt head at home. Squirrels around here would laugh at ya Seriously , I' ve tried the blunt heads and they work on rabbits and birds but I' ve had big sqirrels take a blunt right smack center and fly 30 feet out of the tree only to get up after a few seconds and run right back up the tree[] How many times have ya had a big fox squirrel that you had to shoot more than once with a 22 rifle? Those are some tough critters!
