I need advice on what spine wood arrow for 40# @25" draw on my new to me HH Halfbreed.125 gr tips.
Thanks for the help,
David
35/40 bop 28
Is your draw 25 inches? I'd go 40-45# and add 5# of spine for every inch more than 25 that you draw. Add 5# more if you're shooting a fast flite string.
Most Hills will shoot a spine that is a little under bow weight with a 28" BOP and 125 gr point, so the 35-40 in a 28" BOP is gonna be very close. If you shorten the arrow to 26" BOP, I'd drop the spine 7-8 lb. Some test arrows will prove to be a great help.
Thanks for the help,

We have a 42@26 66" Big 5 in the family collection. Drawn to nearly 26" it shoots 40-45 spine 27" with 140 Hill broadheads 5/16 Acme cedars best. We have a Cheetah that is 37@26 it shoots 38 to 40 spined tapered cedars with 140 grain Hill heads best. The Cheetah did get a shelf reduction, the Big F was a Kramer built and came with a deeper shelf. That is my one point that I made with them, there is little danger of a lighter shorter drawn bow to cause a riser crack and since Hill longbows like slightly lower spines, with the light bows with the shallow arrow shelf, it does not give one much room for wood hunting arrow selection and leave you with a reasonable length arrow. I hate shooting extra long arrows, they are a pain in a back quiver, clumsy to handle, and all of that wood out in front of the bow gives a hard to predict variable when selecting an arrow spine, plus all of the bit by bit testing that is required with extra long arrows. Hill had it right when speaking about net length arrows out of his longbows. If the light Hills were cut closer to center it would be much easier to get a hunting weight arrow to shoot. I also don't trust wood arrows under 35 pounds spine for deer hunting. These lighter Hill in our collection have both killed a number of deer, without one lost deer, and penetration has not been an issue at all.
I'd get 27"bop 5/16 elite arrows spined 38-39-40 and first try 100gr points for more cast and a flatter trajectory,,, if not go with the 125's..
