Of course I can not really tell from the pictures, but it really does look like you bore was concentric with the end of the barrel. So in reality your QLA may have not been a problem.

One of the reasons that TC adds the QLA is to give the appearance that the bore is concentric with the barrel and in a lot of cases it is. When it is the QLA is not a problem in the world of accuracy. The crown at the bottom of the QLA can be.

I think it was txhunter that cut his QLA off also and posted pictures of his barrel after the cut. You would not believe how far it was off center so his QLA was a huge problem when it cam to shooting concicals.

The way TC bores and rifles their barrels can lead to the off center bore. The method they use while it is an universally accepted method it is not always the most accurate by the time the bore imerges from the far end. The worst part is that even if it is off center it really does not effect accruracy but sertainly does effect your thoughts on quality. How to cover up the small mistake - use a center QLA, which normally does not cause an accuracy problem with sabots or Powerblets...

Have you seen this 2 bit drawing that I did a long time ago. It kinda explains what I thought I had come to know... especially after seeing txhunter's results.



I have a library of this useless information
