Need your help on Arrow GPI listing
I know this maybe a stupid question however I need to ask. When I see the Grains Per Inch "GPI" on an arrow shaft for example my ICS Beman Hunter Pros are 8.8 GPI. Is this GPI weight Including the nock, insert and fletching etc? Or is the 8.8 GPI based solely on the arrow shaft alone?
