I' m trying to paper tune my new bow and I' m struggling. Here is my equipment:

Hoyt Razortec
64# draw weight
26.5" draw length
Bodoodle Zapper 400 rest
Beman ICS 400 camo hunter arrows. (weighs 436 grains with practice tips)

I' m new to this but I' m following the instructions in my Hoyt owners manual. I have my paper set 6 foot from my target and am shooting 6 foot back from this. By the tear in the paper the book says that my nok is too high. I moved it down 3 times for a total of about 3/8" of an inch with no improvement. According to my bow square, the nok is low now.

Did I not go far enough down?

Also the book says it could be sign of a weak arrow. Don' t really know what this means. Has anyone had any problems with this style of Beman arrows?

Anyone have any ideas?

Thanks.
