OK, I tried to stay off this post but can't any longer. I abhor choke tubes and all that goes with that discussion. This is my take and doesn't matter if any agree. My bucket list sporting clays gun happens to have right barrel full choke and left barrel mod or even maybe IM. Any way tight. I started with a big pocket full of spreader loads but have found that when I put the barrels in the correct place, bingo! I am down to only using 5 or 6 spreaders(close rabbits mostly) and enjoying the guns choke configuration.
Bottom line for me is--learn to shoot the gun! Some one wiser then I once said chokes are for inches--lead is for feet.
I am still learning BUT having a great time doing it.
