Hey guys, I am finally going groundhog hunting, There are quite a few of them that live in a field just below my house. The gun I will be using is a mossberg/cbc .22 LR. Most of my shots would be between 15-30 yards, although my gun is accurate to about 50 yards. What in your oppinions would be the best ammo for groundhog hunting? I have a box of cci stingers, how would they do on some groundhog at 15-30 yards? Thanks,nc.hunter. ps. My .22 is semi-automatic.
