If that's a 100 yd. 3 consecutive arrow group, my hat's off to you. It's a challenge anytime but really a challenge unless you have calm winds.Nice shooting gents.
After a fine tune up and installing a CCD on my Bear constrictor, been shooting out to 100 daily.
I'm not hole in hole but for Bloodsport .003" arrows, I'm happy.
My experience has been that .003 arrows can group just as well as .001 arrows. I've measured the straightness of many so called .001 arrows and found them to be closer to .002 and even .003 straightness. Likewise, I measured .003 arrows that are closer to .002 straightness. In other words, arrow straightness can be very misleading.
My experience has revealed that arrow spine consistency is what matters most followed by weight consistency. But if you have your own spine tester and make up your own arrows, you'd be foolish not to spine index them as well.
