i'm a newbie to coyote hunting. i have been out a few times with no success YET. but i had quite a few run in on me while deer hunting this last gun season in illinois. i was going to head out with my new stevens .243 and want to bring the shotgun along with me. i have a fixed choke barrel in mod. what is a good shell for yotes in that choke? it's a 2 3/4 chamber also. thanks
