Okay. I swore I would refer all further requests for legal advice on this forum to that great legal scholar, Roundball, but I will weaken this one time.
Since you didn't attend law school, You can't know anything about the Commercial Code, or the Implied Warranties for Fitness of purpose, which govern every product sold by manufacturers in the USA. In addition to the expressed life-time warranty that T/C is noted for on all its guns and parts of gun, there is also an Implied Warranty of Fitness for purpose that requires the Factory that made the barrel to stand behind what it has made and sold. It doesn't matter if you are the first buyer, or the 10th. If the barrel is not properly dimensioned, they need to make good on it.
The barrel didn't shrink after it was made. Its didn't tighten that bore after it was sold. It was made incorrectly. It got past the inspectors. It happens. The factory doesn't want barrels like that getting out its doors. It may not have even gone out the front door!
So measure the bore with calipers. If you don't have calipers, then stop by a local machine shop and ask them to measure it for you. Take a 12 pack of beer as a present to the guys and they will jump through hoops for you. Most machinists are gun nuts, too, and getting a chance to look at anyone else's gun is--well-- a lot more interesting than making the 5,000th widget that day. Once you know exactly what the dimensions of the bore are, you can call T/C, talk to them, and expect them to tell you to send the barrel back for a new one that is correctly dimensioned.
YOu should not have to use a smaller ball the size of .433 in order to be able to load and shoot that barrel, if its a .45 caliber. And a common .45 jag should not get stuck in that barrel, unless there is something down in the barrel, or its been bored too small. While you are measuring the bore, measure the Jag. You must may have an Oversized JAG???! :shocked2: :rotf: :hmm: :thumbsup:
