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?
