John-
I can't speak to the TC specifically, as I don't own one with a .22 match chamber. I do own several bolt actions and target pistols with tight match chambers, and all are among my most accurate guns. While a standard .22 chamber can certainly be accurate with favored ammo, I think a match chamber does help in over-all accuracy. One thing to note is that some match chambers can make for more difficult chambering, though that shouldn't be an issue with the TC. A good example is my Kimber bolt action with a tight match chamber, compared to my CZ with a quality barrel, but standard chamber. Both are accurate, but the Kimber more so with a wider variety of ammo, and much more so with match ammo, as in under 1/3 of an inch at 50 yards with Eley and some lots of Federal Gold Medal. From what I have seen of used TC barrels, I have not noticed that those with the match chamber bring any particularly big premium, so for the slight added expense, I would try one..
