Just built some GT 5575s with 100 grains behind the insert, 28 3/4" long, shooting 200 grain points. Bow is 56@ 28" BW MAII. Bare shafts hit where my fletched shafts do. I have moved the nock set from 3/8 high to square and it does not make a difference. I also notice a click upon release. Bow is now suddenly loud.
I have been shooting 3 under for a while now after shooting split for YEARS. Would like to keep shooting that way.
When I shoot split finger with these arrows shoot like bullets.
Any ideas?

I would try moving the nock point up, say to 5/8" above center.....maybe even more. When I played around with 3 under I started at a 1/2" above and moved up from there. Worth a try! Good Luck-Mike
-
I agree - move nocking point up.
-
I agree with Mike...what kind of fletching are you using ? helical ?
-
4" RH shield
-
are they straight or helical....

Aside from your bare shafts hitting where your fletched shafts hit, how do they fly? Straight, nock left, nock high? I agree with moving the nock point up, but suspect that isn't the whole answer. From my own experience, 300 grains up front would make for too weak of a spine under the conditions you specify. FWIW, my nock points for 3 under vary from 5/8" above square to 7/8" above square, with the arrow being nocked under the string nock.

My bow is 56# @ 28, same as urs, and I shoot GT 5575's with RH parabolic.
I have a 100 grain brass insert up front, and 170 gr. broad heads.
Total arrow weight is right around 560 grains, and makes for an arrow that is almost exactly 10 gpp.
I imagine that you would have the same success as I have had if you use that set up.

Two things. First, move your nocking point up to 5/8 to 3/4. Second, and this may or may not be part of the problem, heal the bow a bit more. I experienced the same symptoms early this summer and both were part of my problem. My bow, Big River R/D likes to be healed when shot and clicks and kicks the arrow nock high left when either the nocking point is too low or I don't heal the bow properly. I also increased my brace height by 1/4 to 1/2. I now shoot bullets

What does that mean? To heal a bow?? Forgive my ignorance. Thanks

Healing is having more pressure on the heal of your hand when holding the bow. NOT gripping but letting the bow grip sit in/on your lifeline and relaxing your hand so most of the pressure is on the bottom with almost no hand muscles in play. Understand that the muscles in the hand can cause significant variability in grip pressure and therefore torque and torque causes bad arrow flight. In my case, when I don't have enough heal my groups are erratic and more likely high left. Try it out and see what you think.

RH helical fletch. My bare shafts hit nock high and left.
I have an old GT5575 XT that is just under 28" and has 150 grains of weight, 200gr point, 3-4" parabolic. It flies really well and does not click.
I have noticed some grip issues too. I will work on that.
-
Ok, really worked on my form and raised my nock point. I also added another below the nock. My flight really improved.
-
With 3 under i start my nock point at 3/4 or 7/8 and come down untill its tuned in. I wil most likly end up just above 5/8 or right at 5/8

Had similar problems and figured out my release was the culprit. I watched the moebow "release tips" video and really paid attention to the part about relaxing your forearm and hand and letting the string straighten the hand and arm as I draw it back. Made a HUGE difference and I got rid of the slap and vertical kick I was getting off the shelf that indicated high nock but in fact was bad form. I found I was putting pressure on the nock actually bowing the arrow down as I drew it back...
Relax...relax...relax...that goes for the string hand/arm and bow hand too!
