I have a SX3. It should be the same barrel as yours. I get fantastic patterns with plain old Winchester XX 6 shot 3inch.and a Kicks .670. A buddy of mine told me about Kicks chokes. Before I started using the Kicks I was using Indian Creek and the Kicks patterned way better. Keep in mind that every gun is different and like different shot size and chokes so really there is no definitive answer to what will work the best in your gun.
