Nock right

[Susquehannariverarcher]

So I'm not normally too over the top with tuning. But ive been trying to tune up some aluminum for my bow. I've shot 2117, 2018, and 2016. All full length and all 200 field point. And they're all just about exactly the same nock right. So I'm assuming it's a form thing. Any tips or input?

The bow is around 55-56 at my draw and a not quite center cut. I'm right handed.

Nock right at what distance? What is your draw length?  String material? Type of bow? The spines of the shafts you mention are 61, 67 and 81#. Something in that range should work.

Sounds as if the arrow may be slapping off the sight window, caused by a form problem (plucking), jerking the bow arm, a too low brace height, maybe even too much spine, but that seems unlikely given you're shooting full length shafts.  If your form is decent, at this point I'd guess too low a brace height.  But only a guess.  Lots of other stuff factors in.  Where are the arrows impacting?

[Susquehannariverarcher]

The bow is a 60" mild reflex/delfex long bow from a smaller bowyer. Ive been shooting it or more less exclusively for 3 years now. Always shot 65-70 woodies.

I'm bareshafting at 10-20 yards, my draw legnth is 29" (bow is 53@28), arrows are impacting pretty consistently with fletched shafts, string is d97.

I'll trying tinkering with brace height next.

I’ve found the type of string silencers and how far down the string you place them can make a difference in arrow tune as well. Just something else to try.

A couple twist of the string got all the arrows flying g the way they "should" be according to the spine. Thanks everyone!

So the issue was a too low brace height.  Good to hear I get it right sometime.

Jerry ya got lucky that's all:)

LOL 

Yes by raising the brace height, the arrow leaves the string a tad sooner.

With the lower brace height you had, the string was still pushing the arrow at a time the paradox was happening.

[Susquehannariverarcher]

Yep you were right! I usually don't mess with brace on this bow when tuning because it's been consistent at 8" all the time I've been shooting it. But i have been working on my form a bit so I'm guessing that has lead to the change.

Good arrow tuning video..

I higher brace height will give your arrows a weaker tune.  To a degree.  It seems odd that you have the same issue with those different shafts.
It may well be your grip and release.  I drag my third finger so I understand your dilemma.

[Susquehannariverarcher]

I'm a known plucker and a peaker! So there's that to deal with as well.
