The truth is I have an interest in Archery and wonder how the companies get the speeds they do. I do not use a 300 gr for hunting even though I believe a bow is not stable if one needs to tie a parachute (4 or 5” helical fletching) on it to stabilize an arrow even a fixed blade Brodhead. Any target competition shooter will tell you 5” helical fletch will stop a light arrow down range. I believe if a Diamond 2 7/8” off-set fletch will not stabilize an arrow the bow is not stable. One can buy fixed blade Brodhead now that will work with the fletching to fly true, or one can Accurasize them with a little shop work. I did try tight & loose nocks & with this bow there was no difference. If you call Carbon Tech, one of the people there(I believe it’s the owner) will tell you of people who stabilize Broadheads at about 310 fps.
