heavy arrow spine calculation
Posted: Sat Aug 30, 2014 12:40 pm
so i'm trying to make a set of hunting arrows.
in order to have heavy arrows i'm using 100gr weights with 160gr heads.
the bow in question is an uncut horsebow, probably .4" off centre, with a 14 strand 452x
it is #50 @28 but only drawn to 26-27. thinking arrows need to be about 29"
so the number i've come up with thanks to some help from 3 rivers spine calculator is #65
i expect the mass should total 700+gr [with oregon]
65 was the number i had imagined before using the calculator too, which is nice. but i'd like to know if that sounds too high?
#65-70 were the shafts i figured would be ideal...
any thoughts would be great, thanks
