The Encore is capable of extreme out-of-the-box accuracy in rifle, pistol and black powder configurations.
If you are confident in your equipment (scope & mount), tightness of hardware, ammo and barrel break-in, AND it still wont shoot in a manner to please you, it's likely the barrel.
It also could be your hinge pin, but that can be easily detected by barrel movement when the action is locked.
T/C can manufacture fine shooting factory barrels. But the demand for the Encore and supporting barrels is at an all time high and I think the QC of mass produced barrels is not what it used to be.
If you are setting up a hunting rig and want to use factory barrels, I would suggest ample lead time to work out potential bugs before the season begins.
