I remember an old article that wrung out six-inch heavy-barreled .357 revolvers out to 100 yards from Ransom Rests. I THINK it came out S&W 686, Colt Python, then Ruger GP-100 and Dan Wesson (forget the order) and then Taurus followed by a lighter-framed Rossi in last place. All but the Rossi were VERY accurate. Taurus products seem to be hit-or-miss. I wouldn't be surprised if a good one could achieve the kind of accuracy that the OP mentioned with match ammunition.
