The Myth of Grains per Pound of Draw Weight
It has been widely accepted wisdom that arrow weight
must be a factor of grains per pound.
This inaccurate and erroneous view was further compounded by
the many horror stories and fairy tales of limbs breaking and
arrows exploding if this ratio was not met.
There also have been a minority of people who have held to the
quantifiable and definable belief that arrow weight should be
less to compensate for reduced draw weight and the acceleration
properties of different bows.
This translates to stored energy, and as a safety concern, to
that residual energy the bow system must absorb after the arrow
leaves the string. This is the energy stored “under the
curve”, which is different for various bow setups.
AMO has finally recognized this in an “official” capacity.

A caution is that the arrow spine MUST be chosen correctly.
