I was bareshafting an arrow today. It is a .500 spine. I had 175 in front, 30.5 long. It showed really stiff. I though that was a bit strange. I pull 30' and thought if anything it would be weak. Well come to find out I had another 75 gr. insert in the shaft. It is the Easton Axis shaft, so I didn't realize it till I pulled the front out. I went back and shot it with a regular insert and 150 gr. and it shoots almost perfect...
Is there such a thing as showing a false stiffness in the arrow? Why did it show stiff when it should have been incredibly weak? Weird... Just wondering if any of you have had any such thing ever happen... It wasn't a one time thing either, I redid it just to be sure and sure enough. it shows stiff with the extra weight in it???
