As you said having a practice range nearby is very helpful for raising your skill level fast. I would put it at the top of the list with having good, consistent ammo. That looks great man!

Just thought I would jump in with the net I have been using for the last few years...
I use a combination of the safety net that goes around a trampoline.  Then I hang the trampoline mat itself over that and of course I add a weighted rope type of thing hanging from the bottom to help the net sort of catch the projectile.

Interesting you say that Morphy, I felt the same when I first started properly getting into it. For me I started doing it because of a game I had played and the fact that I had at the time recently purchased a bundle of paracord for a survival kit. I was intrigued more by what I could do with the paracord; and so I searched what I could make with it, the sling came up and it started from that.

At first I was just happy I made something, and I used it for the first time when I went on a hike. I sucked at it, like really bad (stones flying out early, didn’t even know a way to cast etc..) but there was something about it that kept bringing me back. I was super causal for a month or two before I actually started looking into it a bit more, found this site and started practicing regularly and constructing better slings. I remember being very surprised that their was a legitimate competition for it too, and the more I scoured this forum I realised how in depth this seemingly simple sport/hobby/skill, whatever you may call it; how in depth it really is. I feel like when most people start out, they feel like the only person within 200km that even knows what a sling is, and it’s a very personal experience that can be hard to explain.

You can get a trick setup for home practice, or you can go practice out in the middle of the wop wops, or just chuck stones when you feel like it, it doesn’t seem to matter. I find that slings and slinging is at its essence very simple, very accessible and very adaptable. Something that you can do wherever whenever. It’s really cool seeing what people do with it, what they make, how good they can get and the overall enjoyment it brings us all!
