One of my friends has a couple of cougars around his place, normally thats not a big deal but, when they start keeping you up a night, running off with your dogs, and you hear them stalking you at night, they have to go! So he's been begging me to shoot them Ive got a .243 and a .30-06, was wondering if a .243 is enough gun for a cougar, and maybe what the best way to go about it? If we get'um he wants to stuff at least one of them...any help would be great...
