My son is shooting 4H archery. He busted up his hunting arrows already, which is a good thing. I immediately switched him from shooting bullseye to 5 spot target faces.
I want to make up some Easton Axis 500 spine arrows for him.
Here are the particulars. He is drawing 26", and approx 43-44# out of a 50#@28 Bear Black Bear Bow
I have some 500 spine Beman MFX arrows cut @ 27". But it takes a 250gr point to tune them per Adcock's method.
Is the old guideline 1" for every 25gr? That would equate to 31". But his hunting arrows are Beman MFX 400 spine cut to 31" and shooting 145gr heads. He shoots these well and has killed deer and turkey with this set up. So the math doesn't add up IMO.
What length should I cut the Axis to use a 145gr head?
I am just trying to get close, so I do not have to go through the cut shorter, refletch routine, cut shorter refletch routine. I am thinking 28.5".
Any input would be appreciated.
