I am not good at picking wood arrow spine and could use some advice.
I have a Great Northern Bushbow. It is marked 43# @ 26". I use a dacron string with wool silencers. The bow sight window is not cut to center.
I have had my daughter observe me shooting the bow and I consistently draw 29" to back of riser.
I'd like to shoot 30-30.5" bop arrows with 125 gr. field points,Woodsman broadheads.
I have a Great Northern strap on quiver attached.
I am thinking that a 55-60 spine arrow cut to 30.5" would be the correct spine.
I have some 30.5" 68-73# spine arrows and they seem too stiff with 125 gr. points.
Any suggestions appreciated.
I'd shoot 50-55, but that's just me.
You're probably pulling in the neighborhood of 50# at your draw length. The bow is cut 1/8-inch from center. 55-60# should be a good fit. That's where I would start.
You're pulling 52# @ 29" with that bow. I'd go with the 55/60's all so. With cutting them to 30"-30.5" bop they will fly good for you.
