There was a group of Omega barrels that the QLA was not concentric with the bore. TC knows about it and even had a note on their web site about it for awhile.
After reading your description - you have one of those bores as i would bet the QLA is square and equal on the bore.
I would capture that removed part and hang on to it. From there i would contact TC and discuss the problem that you found with them. Might need some pictures for an email. Even though they have looke at the barrel in the past i think you now have the physical evidence to aproach them about a warrany replacement should you decide to do it.
I have both an Omega @ one time 2 Omegas and a Triumph that would and do shoot Bullshop conicals very well - so they do have barrels that will perform... Even their newer Hawken barrels have a QLA on them - so they can do it... when the 'quality inspector' is on the job.
