    In richard middlletons wonderful man powered weapons and ammunition he documents a bulletbow that can put five shots (238 grain) into an inch at 25 paces (mtrs) at between 159 (flewitt) and 206 (payne-galwey) feet per second.<br>Can we equal this or better it with a slingbow or slingshot rifle designed by members?<br>Any one fancy a go? <img src="http://illiweb.com/fa/i/smiles/icon_question.gif" alt="Question" longdesc="17">

    I have that book. <br><br>Several of my crossbows can do that, probably. I am not sure if I am a good enough shooter to hold a one inch target at 25 m with ANY kind of weapon, though. <br><br>I can shoot a lot harder, though. The weapon described by Middleton just does 29 Joules of energy at 206 fps, my medieval style crossbow does twice that. <br><br>In terms of accuracy, rubber has the disadvantage of the cooling effect, causing the power to decrease after cocking until the environment temperature has been reached. To be very accurate, you have to either wait 5 minutes after the cocking and before the shot, or you have to keep the breaks between cocking and shooting very much the same every time. <br><br>Steel springs don't have this problem.
