RE: What kind of arrow speed do I need........?
Somewhere around 260 fps has worked for me. That's sighted in at 25 yards. About 1 3/4" high at 20 and 3" low at 30 yards. 15 yards is not as high as 20 as the arrow is still climbing at that distance. My results have shown that 5 yards and 25 yards almost identical POI.
