I would like to see some patterns from fixed choke guns. I have tried my 20 gauge fixed choke double and not getting good patterns.
full or modified?
Try the Federal flight control wad loads, lead or Hw7. The new longbeard loads may be helpful too.
My gun is a mod/full. I have tried both barrels and not getting good patterns out of either. It has a 2.75 chamber.
Getting a good pattern with a 2 3/4" 20 gauge shooting any choke or load at 40yds if going to be a stretch. 30yds with the Federal 7's is doable and anything over that would just be gravy.
need to try some of the Federal shells with the flight control wad in them, you might be surprised
