Okay, so i bought my 10 year old son a Bear Apprentice 3 that he will be getting on Christmas morning. I know he will be bummed if he isn't able to fling some arrows right away so i have been doing some secret investigating to determine his draw length and what he's capable of pulling back. As of now i have set his bow at 32lbs with a draw length of 22" and an arrow length of 23".

I used to be on these boards religiously and my archery knowledge was pretty good. However these days not so much. So i need some help on setting up the correct arrow for his new bow. From the leftover knowledge still rattling around in my head i want his completed arrow to be around 8g per inch which would end up at 184g based on a 23" arrow. Okay so where i get confused is after i add up the weight of the rear nock and fletching 35-40g, field tip/broadhead 85g, and the insert 20g. When you add up those you get roughly 145g. To end up around 184g with a finished arrow i would need a shaft that weighs 1.69g per inch which obviously doesn't exist.

What am i missing?
