I'll be shooting a bob morrison bow @ 53lbs./28 draw. I have bemon 400 shafts with 50 or 75 grain inserts up front. The full length shaft (31.5 for now)with 5 in. feathers,75grain insert,160gr. stos bh with 43gr.adapters ends up @ 621gr. I'm guesing the arrows going to be around 29.5/30 in. after tuning which would take off 15 or 20gr. & i could drop back to the 50 gr. adapters & take off another 25gr. for the total weight being around 580gr. At 10gr.per lbs.53 lbs. which is 530gr.So am i to much over weight @ either way i go? Thanks for any advise.
