Yet another wood arrow question...Carbon/Wood spine equivalent

[Shawn Leonard]

I mis-spoke and should of said 65-70# spine with 125 grain point and an arrow 30.5"s bop! Shawn

[Big Ed]

I am with Shawn. 65-70 with up to 150 grains up front!!

It's starting to click, but I cheated.

My front porch range for these short days. About 11ish yards.

I'm going to plug in this data into the calculator and see what it shows, keeping in mind the above comment about spine showing stiff on the calc.

60-65 Doug Fir, 263 gr with point and adapter, length shown. Crown dipped and crested and three 5" shields. 11/32 parallel.

These weigh 676gr, 674gr, 676gr each.

Using Stu's calculator I have a -12 form factor with these arrows to show spine within .2 of each other. So, I guess for wood, if I have my numbers entered accurately, the calculator shows about 10lb heavy for me with a 0 form factor.

One good thing is the arrow weight on the chart, for all the entered numbers, shows 674 grains.

I'd say that works! Nice shooting.
