100 m target slinging - into the sea

Here I was slinging at stone targets out in the sea sitting around 105m (estimated from Google Earth) using a 28“ sling and random stones (very, very nice random stones). Featuring Archaic Arms and Acroballistics. AA had a total of 12 hits on the day (including a target at 175m). Acroballistics had a left handed hit, but the camera died. I had 3 hits.
