Shooting houses present a unique set of challenges. Unlike a ladder stand or climber, you're body isn't locked against a tree or rail. In an old office chair or stool, which seem standard equipment in most shooting houses, its hard to lockout your core for that steady, consistent shot. Shooting your situation then, for the shooting house hunter, is about getting up and getting rounds downrange. Experiment with kinds of chairs, pillows, supports and ways to brace against the walls. Is this 100 percent necessary for 100 or 150 yard shots, probably not. But if you want to be deadly from your hunting position at 300, 350, 400 yards, its going to take preparation and practice.
