how light is too light?

<< < (2/3) > >>

DC:
My Bamboo arrows are all in the 400-450 range and they haven't bothered my bows that I've noticed. I guess it's a progressive thing. The lighter the arrow, the harder it is on the bow but to stick a number on it would be tough. Depend on the bow I would think. Flight guys might have a better feel for this.

You won't damage your bow before you start feeling handshock to warn you. 7 gpp is a s low as I'd go as a rule of thumb. 400grain finished arrows are normal.

BowEd:
Over time shooting 5 gpp arrows will do damage.As Mike said hand shock is a good indicator.I've seen it happen on FG bows.May take all summer shooting a 1000 arrows per week but it'll show itself.Too close to dry fire.Since I like to hunt I shoot 12 gpp arrows most all of the time.I like watching the target wobble on impact and the penetration it gives me on game.

Pat B:
If you are a hunting archer then 10gpp or more is an acceptable standard. This isn't to say that an 8gpp or 9gpp arrow shouldn't be hunted with. For target shooting 10ppg isn't necessary. Seven ppg or 8 ppg is probably OK as far as the safety of your bow goes.. I think most folks are thinking more about speed as the only way to get "good" trajectory where in fact if you are familiar with the trajectory of your set up you can hit your target , whether it's a hay bale or a 10 point buck. 
 Seems to me watching your arrow in flight and knowing where it will end up was the goal of most archers. Now it seems to be by many folks how fast it will get there. I got away from compounds and glass bows because I like to watch my arrow in flight, knowing the trajectory of my arrow and seeing it hit it's intended target.

Del the cat:
I think it's almost impossible to make an arrow too light, as most of the weight is in the shaft, so even a shaft with fletchings and no point will be ok.
The reason is the huge acceleration. I did a back of the envelope calculation and the acceleration is about 300 times the acceleration due to gravity  :o
So that means the arrow that only weighs 1/2 and ounce (about 220grain) effectively has 300 times that as inertia e.g 150 ounces, that's about 9 pounds! So it's a long way short of being a dry loose!

I think the bigger risk to bows is broken strings or arrow nocks shearing off.
