Is he using a 7.4 grain pellet? I just looked at the Hodgdon data for the 17's and was a little/lot shocked by the velocity attained with the .17FB and .17 Rem with the 15.5 ntx.4917 fps with Benchmark in the .17 Rem!! No idea what the accuracy is but holy cow! 4025 with the .17H and the 15.5 grain! I am really tempted to load up some 17 grain Vmax and see what they do.
