I'm no gunsmith, obviously, but I can't understand how this could be attributed to the barrel.
Isn't the surface of the barrel where the scope is mounted parallel to the bore? And, isn't that the case with many similarly designed guns on the market? If so, it would not seem that the barrel could possibly be to blame.
Are you saying that the bores of T/C barrels are pointing downward in relation to the part of the barrel where the scope is mounted?
I'm just not aware of anything else that could cause this "known, frequent" problem. If this is a known problem, enlighten me to what is wrong with T/C barrels. Thanks.
Barrels are tapered, not the same diameter from breech to muzzle. Typically, the mounting surface where the screws are located is left parallel to the bore (if the scope mounts directly to the barrel and not a receiver). Apparently, this is not the case on Encore/TC barrels, resulting in a base/ring/scope assemble tilted a few thousands of an inch.
The location of the scope mounts on these guns is also a little unconventional -- rather than having forward and rear screws for the mount, both sets are positioned relatively close together towards the rear end of the mount. Perhaps this has something to do with the slight angle that results, I don't know.
You're making alot of assumptions to arrive at the conclusion that it can't be the barrel. How many of these guns do you own? How many different mounting systems have you tried on them trying to solve this issue before arriving at this conclusion? I personally own two Omegas with this problem, as I mentioned just helped a buddy with his Encore with the identical problem, in addition to half a dozen other shooting/hunting buddies with Encores/Omegas and numerous threads on this same issue on multiple hunting sites. I tried different bases, rings, and scopes, all of which failed to remedy the issue. T/C may not acknowledge to you that the problem is known, but anybody who spends significant time shooting many of their guns knows about it. They're not going to publicize issues, just like when I called in about the front sight on my Omega X7 they cut me off and said they'd send the correct replacement before I even told them what was wrong with it. Apparently they know they were supplying them with front sights too short to zero, but now 2 years after I bought mine I have heard of more people still having the same issue.
Next time you get access to an Omega or Encore where the Burris rings have not been used or has not been shimmed, count how many clicks are above where it shoots to 100 yd zero and the number of clicks below. I bet you will find it is nowhere near the optical center, as it should be.
