I've been in this discussion before and I have done some testing with my own bow and found one thing to be absolutely true.


Speed,weight,ke,momentum mean absolutely nothing when compaired to a properly setup arrow.



I took a 495 gr arrow at 238 and compaired it to my 356 gr arrow at 268 and they were the same arrow,I filled the 1 with water and put a 125 gr point on it to keep foc around 10%.The 356 gr outpenetrated a piece of wood with a 75 gr point better than the heavy but when I put the 125 gr point on the light arrow it sucked as compaired to the heavier arrow,put the light point on the heavy arrow and it sucked with penetration.Yes the arrows tuned exactly the same because I was using the Nitro Stingers that spine from 60-100#.The heavy arrow always had more momentum and more ke but did not always do better but the differences were usually very minor except for when I used a 75 gr point on the heavy arrow and the foc was way low.


The key is to have a well balanced arrow that is spined right and a bow that you can shoot accurately.Penetration will be fine.Concentrate on the arrow setup and the tune of the bow more than anything.I would suggest to stay in the parameters that the AMO gives and everyone should be fine. www.bowjackson.com has them listed.

For the record ,speed is overrated,even in the 3d game.I shoot 268 to hunt and 3d and most bows today can achieve that and they don't have to be raticall.


I shot today from the money stake and shot 12 up and was tied for 2nd when I left and the person that I was tied with was shooting 280 and this was an IBO shoot counting center 12's.That is pretty slow for IBO.


Just what I have found to be true for me and my bow and your bows may be completely different.
