Let me give you the set-up for contextural purpose...Public and Professional rifle and pistol range within 1/2 mile with shooting there from dawn to dusk every day, 25 yards from shooter to feeder, steady tree stand rest, route of escape is under the tree stand, wait for them to congregate under the feeder, pick one in the 4X scope, wait for it, wait for it, squeeze the trigger rearward, shoot the middle of the "X" between the ears and eyes, light's out, DRT, and the others will mill around a bit and return to feeding right next to their dead buddy...so shoot another one, and again until they get "wise" and depart, or there are not others to shoot. Works GREAT!
Would I go to a place I do not know and ONLY take a 22 LR with me? Depends! Not if it was illegal or the host told me otherwise. Not if I had something equal to or bigger than a .223 to use instead. Not if I had intentions of shooting a massive hog. Just saying though, it can be done, although it isn't recommended. I just do this at my place because I KNOW it works.
