RE: Exocet... not grouping well at all.
Also did you spin test the arrows with the bheads and field tips? Ez to make one, just glue 4 marbles to a board about 11-12 inches apart, 2 at each end close together, insert tip, lay ovet the marbles and spin the arrow. watch for a wobble at the point of the tip. If you see any the arrow will not shoot very good. I even had field tips that had a bad wobble. Please keep us up to date on your progress.
Thanks, Stan
