I bought a 5gal bucket of landscaping "river stones" to use as ammo.  $2 for the whole thing.  BUT lots of size variety from flat pieces the size of a quarter, to near-fist-sized/shaped boulders.

I quickly figured out about what sizes looked and felt "right", and today I took it a step further.  Using a small postal scale I selected/sorted some rocks into 1/4oz weight classes, starting at just 3/4oz, and ranging up to 2-1/2 oz.   I then started slinging.

Very soon, I found out that my "right" size is right at 2oz, ...maybe just a little on the heavy side of that, but still less than 2-1/4oz.    I suppose 60grams would be just right.

That seems pretty light to me, but then, I'm small (155lbs) and old (60+).   The sling I use is 38" from the center of the pocket to the retained string toggle (no loop).   The pocket measures 1-5/8"wide x 7-1/2"long.  Scrap leather & leather shoelace construction.   Vertical underhand spin and delivery.

What stone weights are the rest of you slinging, and with what sized slings??   Can I expect my "right" thrown weight to increase with practice??   I want to start molding standard ammo to see if I can develop any consistency.

Thanks!      mgreenfield

I find that 4.5oz stones are best for me too.  I started out liking lighter stones, but found out later they are less accurate and you can't really "feel" them as you sling.  I use a large knot as a release node.  The design of the sling will certainly bear into the equation I think.
