I'm Trying to set up a 20ga to shoot with TSS. I have a Remington 870 youth model and got a Jeb's .565 but not satisfied with the results so far with Apex straight 9s TSS.

Was wondering for anyone else that might have a Rem Youth 870 set up for Apex 9s, what choke do you use and what's the pattern showing at 40 yards?
