I cannot imagine a barrel from T/C shooting that bad. That is a good caliber and should shoot very well even with factory ammo. I would not junp to the conclusion that it is a bad barrel. Were you using a scope, and was it secure on the barrel? Was it sighted in properly? Is the scope defective? Did you shoot it with the muzzle brake, and was it any better? Don't give up on it, it may just be a simple problem, and a big cost savings to you if you can salvage it.
Good Luck
