did some google searching... stuff about mongol bows. I thought English longbow draw weights were 200lbs? Or is that for ballistas? Guess the sappers are the best archers in existence....
http://www.coldsiberia.org/monbow.htmThe Mongol bow is not as large and long as the English one, but it is vastly more powerful. The draw weight of an English longbow averages around 70-80 pounds, whereas the Old Mongol bow had a pull that, according to George Vernadsky, averaged at around 166 pounds. Chambers states that the pull varied from 100 to 160 pounds. This seeming discrepancy certainly reflects the fact that draw weight varied with the strength of the user, and with what use the bow had been made for. As could be expected, there was a considerable difference in shooting range. Whereas the English longbow could shoot at distances up to 250 yards or around 228 meters, the Mongol counterpart can hit its target at 350 yards or 320 meters and, if the archer is well trained for the task, even beyond that.

Estimates for the draw of these bows varies considerably. Before the recovery of the Mary Rose, Count M. Mildmay Stayner, Recorder of the British Long Bow Society, estimated the bows of the Medieval period drew 90–110 pounds-force (400–490 newtons), maximum, and Mr. W.F. Paterson, Chairman of the Society of Archer-Antiquaries, believed the weapon had a supreme draw weight of only 80–90 lbf (360–400 N).[2] Other sources suggest significantly higher draw weights. The original draw forces of examples from the Mary Rose are estimated by Robert Hardy at 150–160 lbf (670–710 N) at a 30-inch (76.2 cm) draw length; the full range of draw weights was between 100–185 lbf (440–820 N).[9] The 30-inch (76.2 cm) draw length was used because that is the length allowed by the arrows commonly found on the Mary Rose.
A modern longbow's draw is typically 60 lbf (270 N) or less, and by modern convention measured at 28 inches (71.1 cm). Historically, hunting bows usually had draw weights of 50–60 lbf (220–270 N), which is enough for all but the very largest game and which most reasonably fit adults can manage with practice. Today, there are few modern longbowmen capable of using 180–185 lbf (800–820 N) bows accurately.[10][11]
