As said, TC's "semi" custom shop barrels were nothing special, made with the same quality of blanks with the same equipment by the same people as the standard issue barrels. That's not necessarily negative, most of TC's barrels shoot well enough for the average shooter, some better than average. But any custom TC barrel maker will make you whatever you want, including custom chambers, and from better quality blanks. Might cost more, but they are worth it for down range results.
H&R? Some folks do find grape stakes good enough I guess.
