I have looked around at Hornady's website and have found no official word as to the velocity limitations on the 50-Grain SX. I'm considering using them in my old 77V which I believe has a 1:14 twist, but if I have to keep them under 3600 or 3700 fps, I'll just save the time and expense of the whole notion. Any first-hand experience out there?
