Art, you need do dress Patty.
ihookem1, QLA is that unrifled section of the bore at the muzzle which is supposed to stand for quick load accurizer per TC. It more correctly stands for quick loss of accuracy. Often off center, that section of barrel can do NOTHING to enhance accuracy - it can only detract - and does so especially if using conicals. Sometimes removing that section and re-crowning works miracles for accuracy.
The other thing to look out for with a TC is a washboard surface in the bore. If a bullet (or tightly patched jag) seems to feel loose in spots while tight in others - you have a poorly done bore that will absolutely not shoot conicals well.
CVA also uses a similar section of barrel at the muzzle, but theirs is not nearly as long and (so far) has been done accurately. CVAs (those with Bergara barrels) have so far done extremely well for me with both conical and sabot loads.
