Now that you have your scale I suggest that you weigh every component that makes up a completed arrow. I've seen a 7gr spread in the same batch of 4" vanes.
Yep. I just thought the heads should be much better. 6 grns. is the difference between great shafts and ordinary ones. That say's something for the difference. Weighed mine and they are, built, within 1, except for the broadheads. GT pro's, duravanes. I did notice a difference in the nocks. GT's nocks with the screw are 15 and without 12.
Just a need to know I guess (a need to know it's not me mostly) and there's not much else to do with the bow and arrow this time of year. I suspected that in the vanes. It was one of the reason's that made me buy the scale. Gander Mnt. weighed some 4" vanes @ 4 grns. I knew it was time. The guy was blind in one eye and couldn't see out of the other and the scale wasn't digital, but he worked it for several minutes and after coming up from the floor anounced, they were without a doubt, 4grns., for sure.

It's kind of funny now.
