How close to you need to be?
someonemakes it's recommendations on how much your arrow weighs right?? 70#= 350 gr. arrow. 72#=360 gr. etc... how close can you be under that recommendation for it not to matter. 2 gr, 5 gr, no gr???? needs to be that weight or higher ??

None. In order for most of the manufacturers (HCA is the only exception I know of)to cover your bow under warranty you must be shooting a minimum of 5 grains per pound of draw weight.
Remember that 5 grains per pound is the bare minimum that you should be shooting. I prefer to have an arrow that weighs 7 or 8 grains per pound. Not only will it be easier on your bow it will also make your bow much much quieter with a heavier arow.

RE: How close to you need to be?
For warranty purposes you would have to be dead on probably, but how will they know? As far as what is safe to shoot it depends on several factors of your bow. You can't just set a minimum weight for every bow and configuration. If you shoot a slower cam, less draw length or have more weight on your string you can get away with lighter arrows and still be safe. A person shooting a round wheeled target bow with 26 inches of draw can get away with much lighter arrows than someone shooting a bowtech Black Knight at 30 inches of draw length. The amount of power one produces is vast compared to the other. And this in turn effects what your minimum safe arrow weight would be.
Also having good string silencers, Limb Savers and vibration reducing stabilizers helps quite a bit.
Bowjackson's site has an AMO minimum weight chart if you want to look at. Some of my set ups have been lighter than 5 grns per pound and that is an AMO limit, not IBO. Simply because of how innefecient the set up was.

Not to mention there is really no reason to go under the IBO rating unless your bow just cannot get 280 fps for ASA then you can go a slight percentage below 5 grains/pound until you reach 280 fps.

Not sure about this AMO standard but since most bow manufacturer's are basing their warranties on IBO I would stick to that. I'm sure that they know what the likely failures are when a bow is shot under this recommendation, that is why they base their warranties on it, its a safety factor.

You think the manufacturer doesn't know what happened, but believe me, they've done enough testing to put your ignorance to shame.
They also make the final ruling on whether or not they will repair/fix.

5 gpp was put in there by the lawyers and the companies to protect the company. However, I'm not saying that means it's cool to just drop way down. I wouldn't go much below that weight though to be safe. Paul gives a good explanation of why. I've shot my bow at 75# 375 gr arrow and the vibration was no different than with an arrow 70 grains heavier with my Ally.
A friend that owned a shop had a guy that came in with a bow that the guy was shooting arrows that weighed something like 4 gpp with a 70# draw. He said every shot sounded like a dry fire but the bow didn't look harmed in any way.

RE: How close to you need to be?
back when i had my X force the moron at that shop set me @ 73# pull and a 309 gr arrow!!!!!!!!!! I didn't know, he said it was fine b/c it was 5 gr per in" well, My arrows were just over 24" !! Talk about feeling like dry firing!! It worked well all season however, I never had any problems. I didn't know the arrow was that light until Feb of this year. I changed arrows and then sold the damn thing anyway. I asked the question b/c Im pulling 72# and my arrows that I weighed were 360-363 gr. That's only three arrows that I weighed. If you add up the Vanes, the nock, the insert, and the tip the arrow should weigh only 358.25 gr. So I wondered if I had anythat were too light b/c IBO says at 72# it needs to be at least 360 gr. I know that my arrows are short 24 1/4 to be exact. So they are stiff and I only have a 26.5 " draw, but I wanted everything to be alright. I got some good advice from some guys on here so hopefully everything will good.
