Skill: Field Positions
From a relaxed stance, randomly choose a field position, quickly assume it (remember, smooth is quick), then shoot a can. Use any natural rest available, such as a tree, or an artificial one, like a lawnmower or deck railing or even your kids' swingset, to enhance accuracy. (Field positions used without rests are for competitive shooting; hunters can almost always augment field positions with a pack or a natural object.) If using a railing or tree trunk to support the rifle, for example, put your weight on your forward knee so you can use your rear knee to brace the elbow of your trigger arm. Keep track of the number of hits.
Drill: Find and assume a solid position and deliver an accurate shot at a can in 10 seconds or less. Next, execute the drill with shooting sticks or a bipod from standing, kneeling, and prone positions.
