Question on Arrow Spine?
My Gran daughter is shooting a Martin single came bow at 50 peak at 27" draw,she using a 8.4 grain easton shaft with 2" blazer vanes.
I was over at the easton chart say at that set up she should be shooting a 500 at 7.1 grains.
I also see on the chart the 400 shaft is a cross over at 51 lbs mark .
I wonder is she should stay with the 8.4 grain at 28" or switch to the lighter 7.1 for a little more speed for deer hunting
will the 500 shaft be a little under-spine
yep she shoot a release
400 shaft fly 20 yard bare shaft like a dime :I wonder how the 500 will work>
