RE: how to measure my arrows..
I'm with you, no bh behind my fingers. I can just see my finger sticking up some time, bearing down on something. Would love too lope some more off the shaft, just can't bring myself to doing it.
Good post Paul. I'd just add that a shorter shaft may get a person into a 400 spine from a 340. In some shafts that's a considerable reduction in weight/more speed.
Trying out the heavier FMJ's, a 400 would be nice, but I just can't make them shorter. Stuck with the 340's at over 11 grns/in.
