21st-century hunting compound crossbow. A crossbow is a ranged weapon using an elastic launching device consisting of a bow-like assembly called a prod, mounted horizontally on a main frame called a tiller, which is hand-held in a similar fashion to the stock of a long gun. Crossbows shoot arrow-like projectiles called bolts or quarrels.
Hunting crossbow. Big game hunting requires a draw weight of more than 35 pounds-force (16 kilograms-force). For larger game such as elk or moose, more than 50 lbf (23 kgf) is suggested. Most male American archers can draw a bow rated at 50–60 lbf (23–27 kgf), most women 30–40 lbf (14–18 kgf). [6]
Thus, if other factors are equal, a standard Han dynasty crossbow with a ≈387-pound (176 kg) draw weight and a 20–21-inch (510–530 mm) powerstroke would have comparable levels of power to a medieval European crossbow with a 1,200-pound (540 kg) draw weight and a 6–7-inch (150–180 mm) powerstroke.

The original draw forces of examples from the Mary Rose are estimated by Robert Hardy at 150–160 lb f (670–710 N) at a 30-inch (76.2 cm) draw length; the full range of draw weights was between 100–185 lb f (440–820 N). [8] The 30-inch (76.2 cm) draw length was used because that is the length allowed by the arrows commonly found on the ...

Since the arbalest was much larger than earlier crossbows, and because of the greater tensile strength of steel, it had a greater force. The greater draw weight was offset by a shorter draw length, which limited the total potential energy that could be transferred into the crossbow bolt. A skilled arbalestier (arbalester) could loose two bolts ...
