Don't forget to try HeviShot as one of your ammo types. Has the reputation for very tight patterns, so you may not want to use the turkey choke but maybe something more open.
Glad to hear these barrels take a standard Invector choke. I have a Citori that uses the standard Invectors, so if I end up with one of the T/C Encore barrels I'll be all set. A friend's Stoeger shotgun used the Invectors, too.
