Is there any obvious reason why my arrows are too stiff?
I tried following the Easton guide - did I get any of the settings wrong? Also do I go one step weaker or more?
My AMO Draw length is 30 7/8"
The poundage of the bow is currently measured at 34.3lbs
The way I read the arrow chart put me as a T7, with the poundage making it very close to a T8.
For ACC arrows the T7 box gives these two options:
3-18 560
3-28 500
For ACC arrows the T8 box gives these two options:
3-39 440
3-28 500
So I figured the 500 spine were a safe option.
However I tried a bareshaft tune.
I installed a matchstick to make the pressure button solid. I set the centre shot (as best as I could - using tape on the limbs with marks for alignment) and I set the rest height. I shot fletched arrows and set the sight until they were going into the gold (20 yards - 60cm target). Shooting the bareshaft goes to the left missing the 60cm target altogether (but hitting the boss).
I have 85gn and 100gn points. The 100gn points are a bit better but it isn't enough of a difference.
My limb bolts were nearly all the way in, I only had 3/4 of a turn left. I have tried winding that in (But haven't shot again yet) - however the poundage only went from 34.2 to 34.3lbs - so I don't think it will make a big difference.
Is it worth trying a bit more weight to weaken the arrow, or is my FOC going to go too far out?
I forgot to say my bow is on the maximum recommended bracing height.
