Of course, much of the confusion and disappointment was because we are dealing with such an amazingly accurate crossbow and our expectations are about a mile high. Remember, using the same arrow and broadhead I have been getting 1 to 2 inch two-shot groups out to 100 yards. Prior to culling, I have seen 5 and 7 inch five-shot groups at 50 yards. (Again, can you imagine the hubris to be complaining about that kind of accuracy
Once I conceded that the arrow/broadhead combo is not going to give us good groups with multiple arrows without serious culling I made quick progress.
I think the key is to cull at 30 to 50 yards where you are not as likely to loose arrows. If I were starting over, I would still buy Phat Heads for sure. If I were serious about it I would buy not less than a dozen Phat Heads to get me started. I would attach them to 12 arrows right away and start shooting all of them for groups. Number the arrows and keep track of the POI of each shot with each arrow. Quickly eliminate any that shot poorly at these close distances.
Then move out to more serious ranges with those that grouped together at, say, 50 yards. I now have 5 arrows that are good out to 80 yards. Four of the 5 gave me a 4 inch vertical this morning and horizontal was 5 inches. I'll try these same 5 tomorrow am out to 100 yards and maybe further if the wind is low enough.
All arrows even though they are the same size and weight have slightly different spines and
tuning the broad heads to the Fletch and weighting them will not produce the optimum results.
Numbering the arrows and shooting them out of order and logging them on the target will give
better results after shooting 4 or 5 times (Groups)
The reason for mixing them up to shoot them is to avoid shooter error. (The first time I tried
numbered arrows after a few shots I caught my self allowing for the errant arrow by holding
off center). I guess I just wanted them all to shoot perfect.
So I just started grabbing any arrow and shooting it with out looking at the number.
After I sorted the good shooting arrows I tried to adjust the type, weight and orientation of
the other arrows and weight seemed to have the most effect but sometimes just rotating
the broad head would correct it and as long as it hit the same spot I used it.
But those arrows were marked to keep them separate from the others because they had to
be set up differently than the "Good" ones.
Just the way I tune arrows.
