1-LOAD 4-1 SHOTGUN DRILL
Quad loading is made easy with these Safariland Model 086 Double Shell Holders. 

Set a target (steel or paper) at 10 yards. NO SLUGS! Lead birdshot only! Start with muzzle at low-ready (pointed just beneath the base of the target stand). On the beep, deliver one hit, quad load or load two and two quickly,  and deliver a second hit. 

Tips: As the first shot breaks, the support hand should be moving to grab shells. LOOK at the shells as you grab them and look at the loading port while loading. It sounds simple, but some stay target focused.
