arrow weight/f.p.s

[Jotis]

Is it worth changing arrows/components over 20 grains? I am looking to gain a few more f.p.s

You will gain around 7 fps.

It's not uncommon for me to have 125 and 100 gr heads on arrows while I'm hunting. At 40 I add a yard.

The first question is - Where are you now?

To me, 20 grains isn't worth the effort in itself. But if you were to combine that with something like adding 5# of draw weight or a faster bow then it's measurable.

I made an arrow speed calculator the other day for people to play around with. It's based on a good sized dataset with actual chronograph data at varying lengths and weights. I find it a little more accurate than others out there, but none are perfect. This one lets you detune the IBO so it's closer to reality. Most bows I find are about 5% lower than advertised.

What does that extra few fps get you?

 

[Dylan Sluis]

To me no. If it was as simple as put a different field point on the front than ya sure. But if you aren't changing anything other than the weight it's not worth it. And like asked above what is your fps now?

No 10-20 grains is not worth changing the arrow set up. you will not see a performance difference.

Only you can answer that question. What is the main driver for you wanting a faster arrow? There are some pretty easy ways to cut 20 gr without changing arrows. Cutting them shorter is the easiest, fletching with lighter fletchings, using a lighter broadhead.

One thing to consider if shooting fixed heads is that once you start shooting over 280fps they become much less forging and groups typically open up unless you are shooting with near-perfect form every shot.
