how many grains/lb

sngehl01 · 02-25-2008, 08:11 AM

I know you are supposed to shoot 5 grains per pound (unless you have the new barnsdale limbs or w/e). The reason is so the limbs don't absorb so much energy and stress and crack. But, what if you have an STS? Would this allow you to shoot a lighter arrow, let's say, a 300 gr arrow at 70 lbs, and not worry about "dry firing" or whatever you want to call it. I mean, the STS would stop the string and absorb a lot of the energy. In essence, the STS acts like a big arrow that's too heavy to shoot (or just won't move).

I don't intend on doing this, but I was thinking about it and I didn't really know.

thanks.

I think you mean 5gr per lb of draw weight.

IMHO no and if you did you would void the bows warranty

I agree. It doesn't seem that you have the same type of transfer of energy that you do with the arrow. The sts just seems to stop the energy. I guess the rubber stopper absorbs some but I would not think there is any kind of efficient transfer of energy there.

yes, I meant per pound of draw weight.

and I agree it would void the warranty.

But I'm curious (I'm not going to do it, so I really don't care, but it's just on my mind) if it's really dangerous to do that. It wouldn't seem like it would be to me.

I don't know. Thanks for the replies.
