Good advise above, pattern your gun with either copper plated lead BB or Remington HD-BB. The HD is the better load, but cost more. Remington does have a $15.00 rebate on the HD shot, so that helps considerably. A choke of about .670" - .680" should work really well. But only time on the range with chokes, loads, and pattern paper will actually tell you what works best. It is like sighting in a rifle - it is exactly that important.
