Then practice for the field. Use paper targets because they show exactly where bullets strike. Distance isn't important-your goal is to master the fundamentals of marksmanship: position, aiming, trigger control. Before you load up, find the rifle's natural point of aim, and adjust your feet to bring that point of aim onto the target. Don't pivot at the waist or force the rifle over with your arms. You can't hold it perfectly still, so your object is to hold it where its constant movement is centered on what you want to hit. A sling, with a shooting loop that adjusts independently of sling length, helps with this.
