If you’re a trap shooter, you’ve no doubt patterned your shotgun for your load of choice. If you shoot, say, No. 8s and you usually shoot singles, it’s nice to know what your pattern at 30 to 40 yards will look like if you want to consistently smoke those orange disks. Similarly, if you’re a turkey hunter, you’ll want to know at what distances your load of choice is lethal through your turkey choke. But have you ever bothered to take your home defense shotgun out for a spin to see what it will do with OO in tight quarters at domestically likely distances?
