As a non-native speaker, I have to guess what "draw weight" is. If it
is the force of the draw of the string, measured in kilograms (1
newton = 0.1 kg) then the weight of Mongol bows could reach 60-70
kilos (a pound is 0.4 kg), as the hardest draw ever documented (note
this!)is with the
Turkish bows of XVIII (about so) century, stated at about 72 kilos.
But of course, draw weight influences on how far the arrow flies not
directly. One of the guys I trained changed swordplay& martial arts to
bowmanship. Being a Moscow Aviation Institute graduate he gave me a
thorough survey of the relations between the distance of the flight,
effort to pull the bowstring and the bow material properties. Being a
philologist only :-) I got only that the correct method of checking
the bow's real capacity lies in measuring the range (or the weight???
can't remember...) of a half-drawn
shot, and that the traditional method of attaching the dynamometer to
the string measures nothing but the flexibility of the bow.
Of course, if I understand the term right.
