Many hunters are making the switch. Smaller upland birds are easily harvested using sub-gauge shotguns in 28 and 16 gauges and .410 bore. If the distance is right, hunters are even taking turkey with these smaller gauges. RIO demands the highest quality shell construction and the sub-gauge line is no exception. Whether you shoot 16, 28, or .410, in a broad line-up of shot sizes, payload weights, and velocities, you can be sure that RIO's manufacturing experience and attention to quality control puts more game in your bag.
