I've been using the 120gr TTSX in my Ruger 260 since shortly after it's introduction. This rifle was trouble from the start - horrible trigger, mediocre accuracy (1 1/2 -2 inches). I put in a Timney and began handloading, with my best loads (with both the Sierra 120gr Prohunter and the 120gr Nosler BT) hovering in the 1 1/4- 1 1/2 inch zone. Made a direct swap with the TTSX, absolutely no other changes and groups shrank to an honest inch, sometimes under. Bullet performance has been outstanding, both on whitetails and antelope. I once inadvertantly ran a magazine of this load through my Forbes 260 (for which I was trying to find a load for the 127 LRX) and was gifted with that rifles best group to date- sub 3/4 inches for 3 shots. Have yet to get the LRX to get near the one inch mark, let alone under it....
I don't know if I would classify this as a long range bullet, but it's certainly working out well on the sub-300 yard game I'm shooting.
