Black Frog, Thanks for the info.

A couple of points I probably should have stated in the first post.

We are doing this on my sons bow, and he reminded me that they were cocked up a little also. We were only at 10 yards when we did this. is that to close?
We were going to shoot back farther but we ran out of light.
Could the left / right be a torque issue? We will check the center shot tonight and make sure it' s O.K.

Question? Is bare shaft testing for the most part only used when tunning for broadheads, or is it a good tool for all types of shooting?

Currently he is only set up for target shooting, It will be another year before he is old enough and strong enough to go hunting.

Not sure if it matters but his current set up is:

Hoyt Banshee
35 Lbs.
20" draw
23 " ACC 3-00, 3, 3" feathers w/50 grain bulge points
release
string loop
TM Hunter rest.
