My experience with the TC factory barrel has not been good.
I purchased a .223 SS 26" factory barrel for my Encore (stainless, synthetic), and although I have gotten sub MOA groups on occasion, mostly, my groups are greater than 1.5 inches.
Initially, I broke it in by cleaning after each shot for the 1st 10, every 5 shots for 20 rounds. The cleaning products I use are Shooter's Choice, JB Compound and Barne's copper solvent.
I have a 3x9 Leupold Vari-X II scope on it; I have tried both Weaver rings and bases, and the Leupold QR rings and bases. Used lock-tite on base and scope screws.
I have a Bellm 1X oversize hinge pin in it.
Have tried the flat washer trick in a effort to relieve pressure on the barrel caused by the forearm.
I have tried several different handloads using: 52 gr. BTHP match bullets (Sierra and Hornady), 50 gr. V-Max, 40 gr. V-max, 52 gr. A-MAX, and 50 gr. Speer TNT. Powders I've tried include: BL-C(2), IMR 3031, and Accurate 2230.
Have tried factory ammo ranging in quality from S&B to Federal Safari Match grade hpbts.
Did all my shooting at a public range (Rio Salado, east of Phoenix) off of a concrete shooting bench, using a rabbit-ear sandbag under the stock and sandbags under the forearm.
Have never wrote down everything I tried before. This is kind of depressing. Anyway, I plan to box this baby up and send her back to TC and see if there is anything they can do for me.
