7.2 GPP?

[kmc06005]

I have been shooting 28.5 in Easton 2016's out of my 67lb longbow with 125 grain heads. I used stu's calculator to figure out what I needed, but it only works out to a 452 grain arrow. Is this okay or should I be doing something different.


Thanks,

Casey

p.s. the arrows shoot great, I've just observed most people shooting much heavier arrows (10 gpp) and was curious if mine would be okay for hunting.

I also have some cedars that shoot great, but I dont know anything about their weight etc.

They may be flying great, but less than 8 gpp would void the warranty on most of my bows. It puts a lot of strain on the limbs, all that energy not taken out by the arrow.

wow yess  id go like 2219's and foc weight them . what are your specs . bow, draw ect...?

Most of the guys and gals will tell you that is a little light for the weight of your bow. It probably shoots a really flat trajectory and fast. Do you notice any hand shock in your bow hand when you are shooting.

I dont have a great deal of experience but the weight of the heavier arrow absorbs the energy of the bow limbs after you pull em back. (the theory is that the limbs could come apart after shooting lots and lots of lite weight arrows)

Find your self a 600 grain arrow which is still under 10gpp and see if you notice a difference in your bow hand.

My thoughts respectfully submitted.

Couldn't tell ya a thing about Stu's calculator, but that's light, I'd go much heavier, I think you'll like it, I know your bow will, Good Luck ...

[kmc06005]

Thanks for the quick responses.

My bow is a BBO 66" ntn, 67lbs at 28 in.  

What about the cedar arrows I have, they are 28.5 inches long and have 100 grains up front.

Is stu's calculator just throwing me off?

Should I just shoot for an arrow at the correct draw length with 8-10 gpp?

[**DONOTDELETE**]

is it a selfbow?

[moebow]

kmc,  I'd also suggest that your 2016s are too light in spine.  2016s seem to work best in the high 40/low 50 pound bow weight range.

Thanks guys for all the help. Let me just say publicly that ERIC THOR IS THE MAN!

He has gotten me straightened out. Thanks again to everyone.

[eric-thor]

not the man .
 just like to help,when i can. hope it works out for ya let us know how it goes.

You may wish to take a look at the gpp poll thread titled "What weight are you shooting"

The results of this poll should give you a very good snapshot of TG member choices for their gpp set-up.

[Flying Dutchman]

He, that was MY poll!  :D   I am glad it is being appreciated and reffered too! I just saw that over the 500 members reacted, GREAT! The majority (63%) is shooting between the 9 and 11 gpp. 10gpp would be a very good startingpoint. Stu's calculator is a great tool and right on, but remember: garbage in = garbage out! All data you put in must be right. Especially the center-cut option deserves some attention!

so Mike...what did you do about the weight?  add weight inside the shafts?  I have some 2018s if you need them...or more woodies...

Bob,

I think I'm gonna go with 2018's with some weight up front.

[wingnut]

With a BBO you are shooting too light an arrow in my opinion.  That's a lot of shock on an 'all natural' bow.

I like at least 9 gpp on any natural bow and usually 10.

All my bows are shot with at least 9GPP arrows!

Honestly, if you're a hunter, why practice with light arrows and hunt with heavy arrows? Might as well practice with heavy arrows, and get used to the trajectory and all. Besides, heavy arrows are kewl.

[SveinD]

Cedar arrows usually weigh around 11,5-12,5 grains per inch @ 11/32 thickness, so unless you up your spine and frontweight, you will be shooting about the same gpp... Though in a hunting situation, that is a good thing anyway!  

[Orion]

That's on the light side for cedar, Svein.  I have a lot of 11/32 POC arrows that average 15 grains per inch or more. That's just the wood, finish and feathers, not including the points.
