Hey Doc, VV barrels is a good company and makes some very nice barrels. As stated above, "do you reload at all?" Or are you only using factory ammo? One of the big things when it comes to accuracy with a TC is headspace. What you will need to do is get you some feeler gauges in .000" and up then measure the gap when in the closed position of the barrel and the breech face(with an empty chamber). Write that down in your notes so you wont forget later on. Now, when a round is chambered to get the utmost accuracy you need .001" gap between the case head and the breech face. When using factory loaded ammo it is almost a given that you will have too much O.A.L so that when you close the action you most likely have to close it with a firm flick of the wrist so it will close. That in turn can cause undue pressures higher speeds and so on. TC's do not like this, you will need to start with my suggestion and also keep in mind as it was also stated in the post above is where/how you rest the forend the closer to the trigger guard the better. Two other points I may add. One, would be a trigger job and the next one, would be to make sure the barrel is floated. Although, it is a barrel from VV I am almost sure it has the hanger bar system on it.
I hope this helps and if you have any other questions you may pm me and I will help you out any way I can. If you need a trigger job let me know I have done hundreds of them and I have all the parts.
