My low spine, lightweight cedar arrows come in around 500 grns. (Only use them for off-season practice with lighter 50-55# bows.)

I build my fir, larch, birch, and ash hunting arrows to 620 grns. My maple hunting arrows are 675 grns. Hickories are 740. My purpleheart hunting arrows are 775 grns. They all perform very well with 60-65# all-wood hunting bows and pack a pretty fair hit on game. Their stout mass:draw weight ratio does an exceptional job with creating a silent shot.

My 36" oak "war arrows" tip the scale at 1100 grns. I only shoot them for kicks, though, as they tend to have a little drop.
