    <font face="Courier New"><font color="darkblue">Does anyone have any real graphs of the ballistic curves, over distance, for a slingshot ?......</font></font><font face="Courier New"><font color="darkblue"><br><br>Obviously this will vary with the weight of the ammunition used, and the length of pull; along with the strength of the rubbers used.<br><br>My draw is not butterfly method, but to an anchor point on face, which is as far as the bands on my current cheap, Asian, wrist brace rubbers will stretch.<br>Being 30 inches, or 77cm; give me a break, my arms aren't that long being a 168cm, or 5' 6" shorty.<br><br>I use nearly 30mm hex nuts, or just a bit over 1 inch; so they are weighty, and do some serious damage.<br><br>However I have found beyond about an inch or 2 at worst, these fly pretty flattish out to about 20 meters, then they drop off fairly quickly over distance.<br><br>So I am curious about others experiences with much better quality rubbers used, and ammo types, by most forum members.....okay ?<br><br>P.S. Sorry I made an error for a few hours, and wrote little drop for 30 meters; when I meant 20 meters, or just slightly over 60 feet for those using the old scale....okay.<br></font></font>

    every bandset/drawlength/... is different, so there won't be graphs that fit for all.<br><br>if you are a bit smarter than me and measured the (average) acceleration speed with a chrony, you could calculate the (inaccurate) graph by including gravity, weight of ammo, size and shape of ammo, wind/rain/snow circumstances, shooting angle, ... and so on.

    I'm sure with a big enough brain, one could make a formula that takes into account all the variables. But I think we're taking Physic's PhD final paper stuff here. Anyone here?
