A bit more about that “killer” ammo real quick, because it is innovative what Winchester has done with it. The shot inside a Rooster XR load is held together in a block of hardened resin (as shown in the photo above). When you fire the shot, the resin shatters and forms a buffer that protects the pellets from deformation as they leave the gun barrel. The round pellets fly straighter and tighter—and hit birds with devastating results. One afternoon, after a hunt, we fired Rooster XR at paper targets from 10, 20, 30, 40, 50, and 60 yards. Conditions were far from ideal, courtesy of a 30-mph crosswind. Still, as you can see in the photo collage of our targets (below), the results are pretty impressive—almost as impressive as the number of roosters we were beginning to pile up.
