This is a paper calculation but if you are wondering what weight arrow you should be using for your trad. rig I have come up with an answer. 8-9grains per. pound of bow weight. This assumes an average trads. speed and the drop off from peak speed due to arrow weight increase. There is a cross from least to most and then least again. That area of peak energy developed in the arrow is at 8-9g.p.p.. F.Y.I.  |

Thanks. This is going to be my next purchase. I have to go back and read your BH weight reply, too.

I have a question about this. I have some wooden arrows, 11/32 port orford cedar, and total arrow weight with 125g broadheads is 480g.
At 8-9g per pound my arrows should weigh 400-450g. Do you know how many inches I should cut off my shafts? They are all fletched up and everything so I dont know how much the shafts weigh. My draw length is 4 inches shorter than my arrows length, so I can trim em if need be. I was just going to leave them a little long figuring the extra weight wouldn't hurt.

Sorry for the long delay on the answer  I would keep those cedars 2" in front of the riser and eat the X-tra weight The 8 -10 rule is a rule of thumb and not a hard fast rule  As long as the arrows are spined for this bow at this new length you'll do well to keep a little weight forward on those heavier shafts. |
