head on moving target
Just as a side note, have you ever tried to hit a rabbit coming head on at you at a dead run. it is almost impossible to not shoot over the top of them. A rabbit size target is much bigger than the area you have to hit on a hog. it is better to let the rabbit pass you, turn and shoot. I carry a 44 mag and that is more so i have something solid to beat them with if they knock me down.
