Grain?

What's all this about grain in arrows. I know what grain is in wood but what does it mean in an arrow?

DiGI,

That's right about grains being a weight equivalency.  Just to let you know though - If you go to your local hardware store and get dowels, be it poplar, or oak or whatever and are going to start fiddling around making arrows, MAKE SURE that the wood grain isn't running off the shaft, that is, it's straight through the length.
Runoff's on the arrow shaft can split and seriously damage your hand.  It's happened!

When it comes to shooting the bow is 50% and the arrows are the other half.

Grain weight is a very archaic midievel measument, the standard was 7000 grains of wheat to the pound.  437.5 grains per ounce, 15.42 grains per gram. 

It's pretty handy measuring system for arrows because there is a "rule of thumb" of 10 grains of weight for every lb of draw weight.  i.e. 50# bow shoots 500 grain arrows.
