Opinions may vary, but my preference would be to use #7 1/2 shot out of an improved cylinder or modified barrel. Hope this helps. All the best...

I also use 7 1/2's, however I would say imp .cyl or cyl

#7 1/2 and the most open choke you have.... if you have choke tubes, a Skeet tube or IC will work. They are easy to kill... just hard to hit.
