Start with your rifle held in the low ready position, with the muzzle at a 45-degree angle pointing downward at the ground between you and the target. Place the butt of the rifle near the top of your shoulder.
On the "up" command, raise the rifle in a smooth motion, and bring the sights up to your eyes without moving your head.
As the rifle is coming in line with the target, flick the safety off and start applying pressure on the trigger, thus "loading" it. Continue to squeeze as your sights line up on target, breaking the shot as soon as the sight picture is correct.
