The formula for the kneadable concrete is as follows:

1kg coarse sand
1kg fine quartz/silica sand
1kg Cement
500g Cement based tile adhesive
2% by weight of fiber
600ml Water

I tried a Kibbeh maker today but I had no end of problems with the unmoulding. Do you use anything to stop the clay sticking?

Tested today;
600ml of water was too much, I had to add more of the other ingredients. The formula needs a bit of revision, as it doesnt behave quite like clay does in my roller, I'm guessing a tad more tile adhesive. I ended up using just the lower section as a rolling surface to form the projectiles by hand. Once they are cured I'll see how durable they are.

I made a few more clay glandes well. They are great to shoot and I've already gone through 10kg of clay. A better constructed roller and a dosing scoop would speed things up, 2hrs of work for 20mins of slinging wasnt quite my intention .

Steel rods can be quite terrifying if they ricochet; especially if you shape them into biconicals

I started with a trough which was also taking time then used a pvc pipe  thinking that a cylidrical shape would be easily shaped into a pill but the pipe was trapping air increasing times and inconsistencies. I ended up using a short pipe cut off that was the volume I wanted each projectile, I picked up concrete from the bucket with that and shaped the concrete by hand.

I'd say concrete wins only in price, it can't win in time spent.(just because it needs mixing)
The good with clay is that maybe you could fire it and be more durable than concrete.

I was searching my practice field for some of the new ammo I've been testing. Didn't find it, but I did find one of those original rolled concrete glandes; a few smudges of tree still on it but otherwise unscathed

You don't need to weigh the clay, though it helps.

Assuming your molds are uniform and made of a higher quality plastic than the really cheap stuff, you simply make a ball of clay that is slightly oversized than the mold cell, shape the clay so it mounds vertically and then compress the top section of the mold on top of the clay so that the excess oozes out the sides of the cell. Use a a cutting tool to cut the excess away from the sides of the cell before letting them dry.
