Standard for testing trad bow

[bowfanatik]

Hi guys
Do we have some standard for testing bow ?

If we have , please post source or document

Thanks

[dbd870]

I don't understand what you are asking?

[bowfanatik]

I asked for standard ,rules...how to measure bow speed ?

It must be a rule ! 50#@28 arrow 9gpp or something like that
   


Because this is really funny , look at gpp , just to get high speed

[highlow]

I agree. A rather confusing question.

[kennym]

Blacky Scwartz (sp) has tested with 9 gpp for years, on around 50# bows.

So I'm guessing that would be about as much a standard as there is.

Pete Ward also does some testing/reviews.

[bowfanatik]

Yesb, I know that . But we have IBO rule 70# , 30" draw length ,5 gpp . Is that only rules , standard ?

[kennym]

I would think the IBO rule would apply more to wheel bows, I sure wouldn't want to shoot my bows at 30" and 5 gpp. I may be wrong tho...

[bowfanatik]

Agree with you ! But do we have some similar rule for trad bow , established from some legitimate organization

[kennym]

Not that I'm aware of, but I'm not always up on that stuff.

[bowfanatik]

Ok Kenny , thanks

I will wait , more gangers to reply

IBO/AMO(ATA)standard is more or less for wheelies (who shoots 5gpp on a trad. longbow or recurve?).
I'm also not aware of a speed test standards especially for trad. bows.
Be carefull with Bodniks speed measurements,It's marketing vs. reality!
There is also a trend over the pond using lighter arrows for a flatter trajectory.
Most of the newbies do not hunt and want a good result as quickly as possible. They won't spend as much time as it needs and they thought with a flatter trajectory it's easier to get good results. Many try to compensate the lack of knowledge over the material which will works for a while but not in the end. They have no time to learn from the ground.
It's like: Whereis the machine who can do it for me to get better? It's a phenomenon of our modern society.
The "Bow Hunter Recurve league" in my country has nothing to do with bowhunting equipment anymore.
Sorry, I'm drifting let's get back to topic.

I think a good standard is as Kenny wrote 50#@28" and 9gpp to compare.
Like Blacky and Pete does and most of my buddies!

But anyway, I am more interested how fast my bow is with my personal specifications.
I'm drawing 31", so it is not from interest for me how fast my bow is @28".

just my2cents

I don't know of any rules either.  Seems the holy grail as far as speed goes was 200fps at 10 grains per pound at 28".  I don't recall anyone hitting those numbers except with hot rod type bows but, I could be all wet and usually am. LOL

Yes, we have an "accepted" standard for comparisons--the IBO/ATA and the old AMO.

IBO) 5 gpp at 30" draw, 70# bow.

The old AMO) 9 gpp at 28" draw

I don't think many of the compound companies even reference the old AMO standard any more.

Thanks Jim!!

Speed/performance will also be affected by things like strings, silencers, nock fit, shooting machine vs. fingers, tuning, arrow matched to the bow, etc.

We have a standard for strings/bow length measurements, but it seems that more ignore it than follow it.  Frustrating for sure.

[bowfanatik]

Of course is frustrating ! How to comapre 5 different longbows ?! To buy all and then ?

[hybridbow hunter]

AMO standart is 9gpp at 30", not 28"

Other than going by opinions on message boards, unless you can attend tournaments or rendezvous where you can shoot them...yes.

Unfortunately, data from a test does not cover what I feel is most important in a bow. I value a smooth draw, vibration free release, and a comfortable grip far more than fps or a curve on a graph.

I stand corrected.  It was/is indeed, 9gpp at 30" draw with a 60# bow.
