Wood arrow spine

Post by gesthuntn » Mon Dec 23, 2019 7:32 pm

What spine wood arrows would I need for this bow? The specs are 40lb@28 and I draw right at 28. I would like to shoot broad heads between 160 and 200 grains. The bow is a Old Mountain Mesa sole by 3 Rivers Archery.

Get a spine kit from 3 Rivers for the arrows you want to shoot, with some below and some above the 40 lb. they will give you 2 arrows in each weight of spine in 5 # increments. So maybe 30-35, 35-40, 40-45, 45-50. Of course you might end up like me, where it doesn't seem to matter and I use them all for target practice, and they all fly the same....

I would start with the spine calculator on the Three rivers site and enter all your information. My guess would be somewhere near 50 lb spine with that much weight up front. Start out with 30” length. :archer2:

I agree with Cherrybow1. Also with your draw length and point weight maybe 50/54 spine would be a good choice. Don't forget to measure in , where your side plate is cut to center or left/right of center. It will make a world of difference.

Just remember a arrow chart is a place to start. many of my hunting set ups down follw the charts but they are deadly and fly like darts

Don't be afraid to experiment.
