I made and used a leather sling some year's ago for a bit of experimental archeology "Hill Fort Defence" for sling stones I used round beach pebbles about the size of golf balls. I don't have my notes here, I was purely aiming for distance, artillery style sort of thing, less of the bullet with a name on it and more generally just aiming for massed ranks and more of a, to whom it may consern affair, practicing with golf ball's I could normally reaching out to around the 140-170 paces on the flat with lanch speeds inexses of 60mph, with a flight time of over 3 seconds, I also used a completely different throwing tequne starting with my back to the target and let the rock go @ approximately 45 degree's. I lanched some golf balls once from the top of the Little Conval hillfort 552 meters near Dufftown in Morayshire with a following wind , never seen them again, must have went 250 yards + with a vertical drop of nearly 300-500 ft , later that day going back down to the car " the car must have been about 200-300 yards out horizontaly with about a 200ft drop off the side of the hill, I let a rock go this time " full force as perusal" and it went for ages , way further than I expected or even thought possible and nearly hit the car , fortunately though it hit the single track road way down in the glen running between the Conval and Ben Rinnes and the rock just disintegrated into a cloud of dust, completely obliterated, now I'm rubbish with physics but according to Netons second law, an increase of approximately 80 mph over the origonal 60mph lanch speed and a crazy distance to boot "
more than enough to put a dent in any centurions helmet "
.
Ended up giving the sling away to a girl fire dancing when I was drunk and couldint find the right type of leather again to make a new one.
Never mind, just to watch a beautiful woman dancing with fire was a show fit for a King.
