You say the T/C barrels are tapered toward the muzzle. I don't know if that's true, but I can believe that. You also say that the area where the scope is mounted is tapered. Again, i can't say.

But if the area where the scope is mountedIS tapered, then the scope would be tipped downward in relation to the muzzle, correct? That would cause the gun to shoot high, not low. After all, as you have indicated, the fix for a gun that won't shoot high enough is to shim the rear mount up. The guy that originally posted could not get his gun to shoot high enough.

If his barrel was indeed tapered as you say, then his problem would only worsen if it were not tapered. I guess T/C doesn't taper the barrels enough.

I am not an expert, but I know the problem of the gun not hitting high enough cannot possibly be blamed on barrel taper and a scope tipped slightly DOWN. Not physically possible.A scope tipped up would cause the gun to hit low, but then the taper would be running in the wrong direction.

What other mystical properties do T/C barrels possess that all the similar CVA designs don't?

I don't own one but I do know a lot of guys that have and I've read plenty of posts on T/C guns. I can't say I've heard much about trouble getting them to hit high enough.
