Hmmm.. I guess I must have been dreaming when I shot my first pig with a 22lr, because at about 10yds I shot him directly behind the ear , he dropped and never quivered, well over 250lbs, shot another in the neck with my .44 mag at about 40 yds , the bullet hit the neck vertabre and followed it into the head, it did take a second shot to finish him , but he was paralyzed and down for good, I guess theres exceptions to every rule
