A friend of mine invited me hog hunting in March, and while I have killed quite a few hogs, with my .300 Win Mag. ,my .270, and even a .45 ACP, I want to use my RRA AR-15 for this trip. Two things I am not sure of, are what bullet I should use, and what optics I should top with it. The hunting will be some stand, some riding around, a little walking, and even some by spotlight. Any ideas on bullets and optics to make this hunt more productive and fun?
