I own a TX 200 HC which was tuned by Rich from Michigan. I have dropped about a thousand starlings with this rifle with 3/4 of them before the tune. The tune took the twang out of it but the accuracy is the same which is awesome. Starlings out to 50 yards are no problem. I just recently acquired a HW 97K with an advanced tune by Paul Watts and it shoots like a dream. I still like the maneuverability of the TX carbine but the accuracy of both is the same as far as I can tell. They both shoot with a nice thud with no twang at all. I could hunt all day with either of these rifles, however, I do a lot of still hunting and don't move too far in a days hunting.
