I started out doing archery with some 31" Easton XX75 Blues arrows, 1916.
I am using a 70" recurve bow with 28lb limbs.
I overdraw the limbs to 34lb draw weight.
I setup the button and tuned the plunger so at 20 yards the unfletched arrows were hitting the target at the same place as the fletched ones.
Everything was good!
A few months on I decided that I would like to try a clicker.
My arrows are way too long so I shorten them by 42mm.
I then have to retune the plunger.
I had to fit the weakest plunger spring and have it on minimum tension to get the unfletched arrows to hit the target at the same place as the fletched ones.
However, it seemed ok.
I then had to shorten the arrows by another 8mm to get the clicker blade vertical on the riser.
The arrows are now fractionally less than 29" long.
If I now shoot any unfletched arrows they go off to the left and miss the target completely.
I have no more plunger adjustment left.
By shortening the arrows I have effectively increased the spine strength, right?
The weird thing is though if I look on the Easton arrow chart
arrow length 28.5 - 29.5 "
Bow weight 30-35 lbs
Arrow group T5
My 1916 arrows appear in group T5
Am I missing something here?
