I tried bareshaft tuning my 28/70 HeliM over the last 2 days and I just cant seem to bring the bareshafts in to group with my fletched arrows. My bow is maxed out at 70.25# and Im shooting 28″ GT XT 75/95′s with 100gr point. Im bareshaft tuning at 20 yrds, my bareshafts POI is about 3″ to the left of my fletched arrows( It started at about 8″ to the left)….Ive tried putting a twist into the RIGHT yoke and taking a couple out of the LEFT yoke a couple times and thats were I got it to the 3″. At full draw I can see my string tracking off the top of the idler somewhat going “outside” and not straight back…..Its not “bad” but I dont really think I should keep twisting the RIGHT side yoke to much more….IM getting a BULLETHOLE through papaer NOW and the bow is grouping good. I walkback tuned today out to 50 yrds and all arrows are withing 1/2″ either way of my string at 50yrds ( Im satisfied with that)….BUT…I’d really like to have my bareshafts hitting closer with my arrows….I recently swapped out my limbs from 60# to a 70# set…All specs are right on…ATA 30″, BH 7″, and my cam timing is just a hair advanced towards the riser…..What are some options?Creed 28/70 "BLACKOUT", QAD HDX, Ktech5 twin, HHA DS XL5519, T5 quiver, Goldtip XT 75/95, Rage 2 blade Hypo's
Joined: 9/19/2007Have you played with the rest any?Id have to run out and see exactly where its at right now….Its either 11/16″ or 3/4″….Creed 28/70 "BLACKOUT", QAD HDX, Ktech5 twin, HHA DS XL5519, T5 quiver, Goldtip XT 75/95, Rage 2 blade Hypo'scentershot is 11/16″ and running the shaft along side idler down to nock point is 1/8″
Creed 28/70 "BLACKOUT", QAD HDX, Ktech5 twin, HHA DS XL5519, T5 quiver, Goldtip XT 75/95, Rage 2 blade Hypo'sjmho on this subject but the the CS is like 13/16″ for the Helim from what I have read on here and I’d try for a 1/16″ or tighter with idler lean to the nock. I’m hoping that my is a help.1. Increase point weight, use 125 gr FPs.

2. Move your centershot in towards the riser by about 1/64″.
If the two recommended solutions above do not improve the grouping of Bare Shafts with Fletched Shafts, then understand this advise by Easton:
“Once you have completed the finer tuning methods listed for Fine Tuning and Micro Tuning on pages 12-14, do not be surprised if the bare shaft impact changes. It is common on a well-tuned bow to have the bare shaft impact a little low and slightly stiff (to the left of the fletched shafts for a right-handed archer).”How does a fixed blade broadhead’s point of impact compare to a field point’s ?
A little update…..I had a pm from a buddy Brian ( gjarcher) who reminded me of a quote in the Easton Tuning guide…

I also sent ontarget7 a pm and he replied saying that he only seen 1 Helim that wouldnt bareshaft tune but the “owner didnt really care because he only shot mechanical broadheads”…this got me thinking….shoot a broadhead and see what happens. I only have (1) Muzzy MX3 here at the house so I screwed it onto a arrow..spin checked it….and let it flyat 20yrds…broadhead about 1/2″ left of fieldpoint( both in black diamond in target)…stepped back to 30 yrds…broadhead about 1″ right of fieldpoint (both still in black diamond)…..Update…..I was trying to get a good 60yrd mark for sighting in my HHA sight tonight and I felt that I was just to inconsistant. All the ” What if’s ” were running through my head about the bareshaft tune and it was killing me…. I flip flopped my top and bottom limb this evening….I just had to know if it would help with the bareshaft…The answer is …..NO…lol. I shot the bareshaft prob 8-10 times after the swap, it didnt change a thing for the bareshaft. The good news is something happened after the swap…what Im not really sure…but the bow is shooting pretty darn good. Im HAPPY with it. Heres a pic of my 60yrd group immediately following the limb swap and (1) of them (6) arrows is a fixed blade broadhead. Im done tuning for now…Ill finalize my sighting in tomorrow and put a tape on.
