My penny’s worth;

One can tune a bow with a proper set up fall-away rest to shoot bullet holes in paper at any distance in a few shots. See my post on bent bow arm.

But to stabilize a Broadhead is a different animal.
If one shoots the common fixed blade broadhead fast on a light arrow with 3” off-set fletching it will fly like a dive bomber on a run.
If you shoot it show enough, & tie a parachute on the end(5” helical fletch) it will be stable.
If you want to jack them up to high speeds, for perhaps setting the first sight pin at 25 or 30 yds to stop confusion there is perhaps a way.
Some Broadheads are sold nowadays that aid the fletching & stop a lot of the erratics.
Or if one in good in a shop the same thing can be done to most broadheads.
Now if you want to know about people who may stabilize broadheads @ about 310 fps you can call Carbon Tech & one of the people there appears to know people who can. You can find their number in most Archery Mags.
