A critical step to picking the right choke and matching the correct shells comes from really knowing the true range of bird flushes. Pace off shots of killed birds, and you might be surprised. I recall a mature grey-phase grouse rocketed out of the raspberries, presenting me with a station 4 low-house shot. I swung and killed the bird, but because of the thickness of the jungle, I believed I had made a 40-yard shot. I paced it out and was surprised to find the grouse at 21 paces, exactly the distance chosen in the 1920s by Charles Davis and William Harnden Foster for their grouse-hunting game of skeet. My cylinder bore matched with a ¾-ounce load of #8s in my 20-gauge provided the perfect spread at that distance.
