Squarel season started here last week and in that time ive fired twice. The first looked like a hit but he took off after wards the second i know i hit it (rolled then took off got blood/hair) ive squarel hunted for a lot of years and have never lost one. I usually hunt witg a 22 or a 12ga with #5shot but these two days ive used. a16ga full choke with #6 shot. My 12 kills em drt but the 16 idj if i need bigger shot or what. Ive killed prolly 100 squarels in my time but neveer had this problem aby ideas what might be wrong here?
