Last night I shot a bareshaft at 30 yards. It was within the 4" bullseye with my three fletched shafts, but the nock end was kicked to the left unlike my flecthed shafts which were straight. Should my bareshaft be straight at 30 yards or is this all I can expect at this distance?
A bare shaft has zero steering correction.
Therefore, any form flaws will show up,
so if you bow hand is not completely relaxed,
and you maybe torqued the bow slightly,
then the bareshaft may not stick in the target straight.
the arrow stiffness is not correct.
If the bareshaft stuck into the target perfectly level,
but the nock was kicked over to the left.....
try this experiment.
Add one full turn to the top and bottom limb bolt.
Fire a few bareshafts if you have them at a comfortable distance.
If 30 yds is comfortable for you, then that's even better.
If the arrow is even worse, more left,
then try the other direction on the limb bolts.
Take off the one full turn on both limb bolts
so you are back at the original starting point.
I like to put a dot of white paint or nail polish
at the 12-o'clock position of both limb bolts,
so I can keep track of where I am.
Now that your limb bolts are back the original position,
take another full turn off both limb bolts.
You are adjusting the draw weight up and then down
to see if that has any effect on the bareshaft flight.
It works, as long as you have good technique,
and good form.
When you can get the right draw weight
so that a bareshaft sticks into the target straight,
then your fletchings have less steering correction work to do,
and your groups will be that much better.
