10 grain difference enough to cause this?
I was given some Gold Tip Series 22 shafts a few weeks ago & I’ve been shooting them for 3-D ever since. I had previously been using some heavy 2413 X7’s. Those X7’s grouped well, but I picked up 25 fps with the Gold Tips which makes the yardage guesstimation part of the game a little less critical.
I grabbed 4 arrows and headed out to practice last night and I found that 2 of those arrows that were consistently hitting about 6” high at 30 yards. Left & right were good but they were high every time. I had only weighed a couple of the arrows when I first got them but I decided to weigh them all last night. The two that were hitting high weighed in at 361 and 362. All of the others weighed between 370 & 372 and they all group well.
Is 10 grains enough to cause those 2 arrows to hit 6” high at 30 yards or is it simply a coincidence? 10 grains is such a small amount that I can’t see it making such a big difference.
