Hi i am looking at using the FederalFlight Control Turkey loads this spring and was wondering what choke should be used in the gun with this ammunition. Should i be using a Modified or a full choke.[/align]

What shotgun are you using? You really need to pattern it to find the best combo barrel/choke.

I use the Federal flight control wad 3.5 inch and, if I remember correctly, #5 shot for my remmington 870 SPS-T with thumbhole shotgun. The choke that I used last year was the Primos Jellyhead and I absolutely loved the setup. I was getting great patterns out to 50 yards away. I took two really nice gobblers in one shot last spring with this setup. If I remember correctly, the Jellyhead will run you around $40 or so.

i would use a a choke that is .675 to .678 as these are wat won the NWTF patternging competitions

Full for sure, even X-full if you have one.
