With RL17 behind the 180s, you just might get between 2750 to 2800 fps from your 20" barrel
Pure fantasy. ...........Ok then! Perhaps you can explain MontanaMarines velocity #s above on this thread from his 20.5" barreled 308 using some RL17??? Maybe he is fantasizing?? Maybe a faster bore in his particular rifle? Maybe there isn`t all that much fantasy to it.
