So a few more stats"
Length is 30.5"
Shaft weight is about 447grain, give or take 2 grain -- except for the #5 arrow, it was 433 grains
finished weight is between 597 (no. 5 again) and 617 grains. The fletches make the other arrows vary by no more than 9 grains. Close enough.
spine on all of them is 61#, with a deflection of .424"-.427" as measured with my digital calipers and a 2 lb. weight. I am shooting them from a 55# osage bow. So based on spine, they fit in the 10 grains per pound, but slightly heavier if you base it on the bow weight.
points are 125 grain glue on field tips --11/32" diameter
The shafts are mildly barrel shaped, as I sand the tip to fit the point and the nock to fit my jig, and then I sand the middles to meet weight and spine.
Balance is at 18-18.25 inches measured from the nock end. I am not sure what that is as a percentage, as I don't know which end that is usually calculated from.
I added a grain of rice behind the cock feather as a physical index, and I like how that lets me nock an arrow without looking at the string.
The arrows shoot pretty flat at 20 yards, and hit what I look at, if I look at the broad side of a barn. --Right now I can put all six in a 2-foot target, but not in a 9-inch circle. Safest place to be is still right on the bulls eye-- you would be pretty safe there when I shoot.
