I hope I'm not being redundant but I've been paper testing my bow today and all I shot was nock high.
I'm shooting a Martin Hunter at 40lbs with a slight cant.

The arrows are right at 400gr with 125gr field points.

Martin recommends a brace height at 7" to 73/4" and I've tried 71/2 to 73/4 but nothing less then that.

I'm wondering if my field points are too heavy? Should I go buy 100gr? I cant think of what else I could be doing wrong.

Any advise?

When paper tuning or bareshaft tuning you should not cant the bow.  Try again holding the bow vertical, and see if the results change.

Thank you sir! Thats one thing I didn't consider.

Play with your nock point......
