Try different shotgun shell brands and shot size, for that pellet density you prefer. Its challenging to place the shot pattern on the bird in flight, hopefully to get the best value out of your shotgun. I use a Beretta A300 Xtrema & maintain the shotgun myself, this model has 3:internal chokes Full, Modifd, and Imp:C. I can't use steel shot through a Full choke only Modified and Imp.cylinder, or purchase a after market external choke for steel shot.
