I don't have a star dot choke at all but it seems that all the guys that do have agreed that the star dot chokes haven't changed anything other than the label. Again, I can't swear to it but that's at least what most have said. Others have said that the new ones didn't shoot the same but honestly, I've had the same brand/model tube shoot differently in the same gun. I think tubes are sometimes like ammo. Sometimes you win, other times you lose. Good luck with yours.
