SA mentions cutting off both ends of the shaft. For me that is standard procedure except for EastonACC's and X7's.
I cut 1" off the rear of the arrow first thing. Then I cut the other end to desired finished length. A lot of the straightness problems with shafts(especially carbons)can be at the very ends of the arrow.
It
may not beneccessary for every carbon, but it can't hurt, and paying attention to all those little details adds up to aid in better and moreconsistent arrow flight.
