Lets say I am shooting 65-70# spined cedars out of my 60# curve. What does a cedar shaft usually come out to in grains?

You'll need to weigh them to know. They can vary quite a bit in weight and still be close in spine.

I am interested in seeing the weights of heavier spines.  I shoot 50-55 spine and my raw shafts have weighed between 10.5 and 11.5 grains per inch.  Thanks for asking this question.

Cedars I have for my Treadway bow are spined 60# to 65# and weigh in over 500gr with 125gr point. The bow pulls 56#@26". You can probably find them heavier.     Pat

mike:
 the bulk of full length 32", 65-70lb, 23/64"diameter raw cedar shafting for the most part will weigh in around 375-400g(50% or better).  the other 50% will be 400-425g. Of course there will be occasional lights and heavies on both end of the spectrum, but this is where I have found the "average" to be.

 Add 50g and drop to 11/32" diameter for an equal doug fir comparison.

It depends on the tightness of grain, etc.  I've seen cedar shafts as high as 450 grains in 50/55 spine. You can't go by spine of the arrow or even the diameter.  Weigh them or have them weighed.

I'm with stump man. Hap

Mine are 60-65 spine 31" long 125gr. field points or 125gr. broadheads 4" sheild feathers and they come in at 525grs. But like the others have said it can vary so you have check yours. ron w     PS I'm shooting them from 2 recurves that draw 51#

In a group of 250 cedar shafts of 70-75 spine I found a variance of 377-560 Grains!

Yep, the spine has nothing to do with weight...Van

Mine cut to 30" for point and a 125 grain head on, weighed 470 grains.
