Halon 6, 29 inch draw 70lb limbs maxed out then backed out one turn (not sure of actual draw weight). Gold tip 340 hunter xt 28 1/2". Some how I ended up with a 300 hunter xt so I shot it a couple times. It was dead nuts bulls eye every time. That got me thinking so I backed my limbs off one turn, got my 340s back out and now my 60 yard groups have tightened up. So is it safe to say that with my bow 70lbs is too much for that length of a 340 spine arrow? This is my 60 yard group after backing the limbs off
