Many people don't realize this and when they shoot the Federal shells they get crappy patterns because they are using a ported choke.. you need to shoot the federals with a non-ported choke.. either use the Manufacturer choke that came with the gun or any non-ported choke from Carlson etc.. you can also buy a specialty choke made for the Flight control wads from Tru-Lok now..
Not being argumentive and I know you are giving the manufacture recommendations..
But mine through three different 20 gauges as well as many others have been the exact opposite.. Two chokes that work a % of the time the Tru Glo SSX 550 and the Indian Creek Ported 555..
The SSX has 2 of the three things not recommended for best results with these shells wad stoppers and tight constriction. The 550 constriction is as tight as it gets basically in a 20, the raised wad stoppers are used to slow the wad and its rotation.
The Indian Creek has all 3 things that are not supposed to work with the FCW raised wad stoppers, porting and tight constriction..
My findings out of three different barrels a 7-8 different chokes as well as countless Fed Heavyweights, is the more and more I disrupt the wad in the manner it is intended to work the better patterns I get.. The FCW wad through the SSX has identical chunks taken out of each rear brake and the breaks are not fully opened.. Additionally when shooting the SSX the wads fall much further from the target than when using a conventional more open choke with no stoppers.. Testing a pile of chokes from the 550 SSX to an open un ported 575 Angle Port non ported the more I went about the conventional recommendation the better the patterns.
On a side note I did shoot a little the other day with the Tru Glo BOne Collector 555 which does not have raised wad stoppers, but a radical porting design.. Out of one gun it faired very well with the porting taking out chunks of the rear brakes and the wad falling well short of the target.
