Well I couldnt seem to get the arrows to float to the same spot consistantly so I guess ill have to wait to try it on my next batch. I think ill be looking into getting a spine checker anyway. But thanks for the tip.
it will only happen perfect if your inserts are solid without a hole that goes all the way through , cant have any water inside the shafts , i always use CB inserts that are standard for the Easton Lightspeeds , there solid , i use them in my victory arrow generly because they weigh 22 grains and it puts me right in the foc range i prefer
