im doing what everyone said above.. for years I just bought shells and didnt bother to pattern them. Ive missed a few birds because of this and not knowing what the gun could do. Im buying 3-5 different types of shells and I have a few chokes here to try. So far, any combo will get the job done out to 15yards LOL.. im interested in getting great pattern around 20-30yards since thats my average shot

its trail and error... Get some paper targets and shells on boring sunday and see what the gun likes
