Thank, that's good to know. What is a good group with a slingshot? I hadn't thought of it before, but could fishing with a slingshot be very effective? I'm not sure at what angle the water deflects the shot.
There are some slingbow kits that come with what you need to fish - I've never tried it, but if you check YT you'll find some videos of folks doing it.
As for grouping from 7-10 yards, I've seen good shooters consistently send rounds through almost the same hole. 1" groupings are not uncommon for good shots. What's interesting is that you shoot a slingshot pretty much instinctively since most don't have any kind of sighting system. You kind of feel your way through the shot and in time it becomes somewhat natural to just draw back and shoot.
