All of this is good advice.  Also, it's a good idea to not throw with all your might.  One tends to tighten up when slinging at 100% power, decreasing accuracy.  Slinging at 80 or 85% of your full strength won't cost you all that much as far as range and hitting power but you'll be much more accurate.  Jaegoor is one of our most accurate slingers... possibly the most accurate.  Watch videos of him slinging... he's never straining.  Everything is smooth and easy.

Thanks for all of the advice, guys; I really appreciate it. I'll keep all these points in mind next I practice!

It really makes a big difference. Jagged, uneven stones have a tendency to go fairly straight then suddenly veer off at strange angles.

   I've mentioned this many times before here. I'm very fortunate to live in an area, South Jersey, that is alluvial.  During the last ice age the ice sheet got as far as North Jersey but never made it to the south. When the glaciers retreated this part of the state was pretty much under water.  Consequently, we have abundant smooth, oval shaped white river stones here.  They're everywhere. 

I'm a bit jealous, ha ha - A lot of the stones around me are rather jagged and/or flat; even when I search though creeks they're not exactly right. Usually I can find a pouch-full of good ones after a few minutes of foraging, though.

So long as you have a bag of high quality concrete and some water you have all the perfect ammo you could ever want. My dream for years has been to make some sort of press where you pull a lever down and it forces concrete into a mold at high pressure. Just looking at the difference between poorly made concrete and Well made concrete ammo I imagine with something like that you could make fantastically durable ammo. Unfortunately that is above my pay grade.

Polly cheaper to just order a pile of rocks from a landscaper or quarry

I think the design is pretty simple and shouldn’t be super expensive to build one but not sure of the ongoing electric costs. The big thing I think would be the constant noise but all that aside I would be lying if I said I’ve never considered it. Stones really are the best reasonable ammunition for day to day throwing. Short of moving to a rock rich area that seems like one way to do it.

I’ve bought river stones before but usually the people around here don’t take kindly to you sifting their river stone pile for an hour looking for perfect stones only to leave with $10 worth. 

Honestly Cap. I think at this point I’m just looking for someone else to do tumbler first. If it works I’m guessing It would just be a matter of time before one showed up on my property.
