1 If you're right-handed, turn so that the left side of your body faces the deer and brace your left arm directly under your gun.
2 With the fore-end resting on the palm, lean back slightly and pull your elbow tight against your rib cage for support. Use your right hand to snug the stock firmly into your shoulder pocket, keeping your elbow level with your right shoulder. If the deer is moving, do not try to track it in your sights; instead, pick an opening that it will pass through, and hold there. When time permits, or the range is excessive for an offhand shot, drop to your right knee and brace your left elbow on your left knee for a steadier hold.
