atomlab 104 Posted February 11, 2013 Report Share Posted February 11, 2013 (edited) itl be way off the mark mate, best to practice with what you use in the field. i use 8mm but if i fire 9.5mm( with the same bands) theres a massive drop.

micckey 106 Posted February 11, 2013 Report Share Posted February 11, 2013 While I've done loads of research on this.Also ive asked others who are better at explaining this than I am.You would have to weigh each leadball or steelball, Then take into account the distance as drop will happen even at one stride differance,,But stood at 15 yards I found a drop of at least 9 inch or more from 12mm lead to 10mm lead at the same distance,There is loads of info about this on sling shot forum ,, Also ppl who will take time out to explain it better than I can, Hope this helps maybe sheffield cattys can post a link on this 1 Quote Link to post Share on other sites
Sheffield Catapults 71 Posted February 13, 2013 Report Share Posted February 13, 2013 I'm not sure such a graph exists Mick. You have to take into account the weight of the projectile and the speed it is travelling at. Steel will also probably travel faster than lead due to it having less air resistance. Everyone will have a slightly different draw distance, band and tube length and also the pouch material and it's size will play a factor into how fast the projectile will travel. 1 Quote Link to post Share on other sites

I was given a realy great explaination from charles on the sling shot forum,He also gave me a link ,, But I have no idear how to post links ,,He realy did take the time out to explain in layman terms verlocity ,fps , ft/lbs , On bigger black powder calibers, On a few questions I asked .. while speed matters ,so does force I find It crazy that something traveling slower can hit harder.. But I think I am going off the question relic asked,, It will just be practice with both on your range as then you will get the answer yourself as one man force will change the outcome of your answer not to mention other factors Quote Link to post Share on other sites
Shamo 319 Posted February 18, 2013 Report Share Posted February 18, 2013 (edited) Your POA (POINT OF AIM) CHANGES VERTICALLY WITH ANY VARIATIONS IN DISTANCE, BAND TYPE, AMMO SIZE, AMMO WEIGHT AND LENGTH OF YOUR DRAW. PRACTICE, PRACTICE AND THEN DO SOME MORE. AS LONG AS YOU ARE AWARE OF THE DIFFERENCES ALL THE ABOVE HAVE, YOU CAN USE ANY AMMO TO PRACTICE WITH.
