My opinion only... 17 may be a little too fast for optimum performance.....we're running RL 22 with 225 Barnes TTSX's in my wife's .338 WM, getting 2950 fps, with acceptable accuracy. By acceptable accuracy....I mean that it's about what we've come to expect from the rifle. It won't win any matches...but is easily a big game rifle to 500 yards. Maybe a couple hundred farther...when everything it done right! memtb
