Nice rifle OP.
FWIW, Bob Swagger uses the 6.5x47 heavily, dumped a large buck at almost 500 yds, on that day his rifle was a 16.5"...and a 136gr.
Speed and energy take a backseat IMHO to placement and proper bullet for anticipated need - to get penetration to vitals w/expansion. Amax work well at slower speeds.
