Poundage Vs Arrow Speed
 

Hey guys,

I just wanted to share with you guys my experience with increasing the poundage of my bow and the effect to the arrow speed. After some changes were made to my bow, (new string, new loop and tuned) my bow was set to 58lbs and was shot through the crono. It was moving at 252 fps. I asked them to up the poundage to 62lbs. The arrow speed only increased to 254 fps.

So I increased the draw weight 4lbs and only experienced an increase of 2 fps.

Seems like the extra poundage isn't worth it. The guy at the shop said that this is exactly how it goes and went on to tell me that he doesn't understand why so many guys want to shoot 70lb bows.

I guess I expected the increase to be more significant.

Well speaking for myself statjunk, my bow at 70 lbs is shooting 301fps. I'll back it down to around 68 lbs in the next 3 weeks just to be comfortable and prolly loose about 5 fps which is totally irrelevant to the arrow or poi. My sights won't even change.

With my bow it is a 1:1 relationship. 1 pound makes 1 fps difference. Again, why shoot 6 extra pounds for 6fps? However, if I was perfectly comfortable shooting 70 or 75 pounds, why wouldn't I? I think the great part is you can shoot what you are comfortable with and not feel like you have to change.

Huntingson,

My thoughts exactly. Ican fairly easily shoot 70lbs and did for a while before I realized that my bow is more than capable at 60lbs.

The standard is 2-3 fps per pound of draw weight. So figure on 20-30 fps for a 10 pound weight range. However some set ups are a bit more effetient and some are a bit less. It would depend on the cam set up, weight on the string and the arrows you use.

The best way to gain speed is draw length, it's about 7-10 fps per inch! This is why so many try to shoot a longer draw length than they need. Or why us people with short draw lengths are at such a dissadvantage when it comes to speed.

Playing with your draw weight is better left to adjusting your bow to your arrows.
