Flight control is the benchmark for tight patterning buckshot. Nicely done. What choke tube are you running? Federal says it's best with cyl. bore but I've had different results. Each and every shotgun patterns differently.
So correct, our Beretta 1301T shoots the Flight Control best with Cyl Bore choke. Our Benelli M4 shoots the Flight Control best with im. Cyl. choke. We tried all chokes in each shotgun and found which choke each of our shotguns likes best for the Federal Flight Control.
