I just bought a 6 pack of the victory VAP TKO's in 350 spine and cut them down and refletched them to my specs. After gluing in my Iron Will's with the snyder core i weighed the arrow. These new arrows are 17 - 19 grains lighter than my other arrows. Has anyone else come across any issues like this? My arrow is cut to 25 1/2" with 3 vane fletch. Using all iron will stuff up front. My thought was that they miss labeled the arrow and package. My Iron will collar that I would use on a 400 spine arrow would not fit the 350 spine shaft. Had to use the correct collar for a 350 spine. Just wondering if anyone else has ran into this.
