I have a small cut over behind my house that im gonna start hunting. Im gonna use my 12ga bc i feel my 7mm or .270 is a little loud for the area. The cut over is thick and about 150 or so yrds wide ( i know its to far for a shot gun). My gun has a imp cyl 2 3/4 barrel so my question is what shells should i use and how far is to far of a shot. Or should i just say f-it and use a rifle.
