Hi Im new to both this fourm and slinging. And I just thought I would like to add my to-sense to ammo making. I just recently made ammo with mortar mix I don't know the ratio I mixed with but it was kinda runny any ways I put it in an easter egg and I threw it at my target when it was dry and it exploded! Is there any way of makeing such ammo with out it exploding? Im now trying to put almost microscopic threads into the mix but I don't think it will help much....my brother said to put a peice of wire throught the mix to stop it from breaking would it help? also would making a dry mix help?

The "Concrete Bowling Ball"  (http://www.concrete.org/students/stu_competitions_bowl.htm) guys often used fibre reinforcing - either metal or glass/ceramic. The trick for glandes seems to mostly be that the size is so small... Have any of the self hardening clay users tried normal clay? A 25lb block of stoneware should only cost 8-9$, and you should be able to pit-fire them in a bonfire, after which you'd think they'd be darn near indestructible.

Welcome learningviolinist,

I'm sure there is info out there on the web for this kind of stuff.  But, you might get lucky here as some of the people have been tinkering with handmade projectiles.  I would think strands of hemp, sisal, or steel wool would do the trick, but I've never tried.

Welcome,

I have made concrete balls from "high stength concrete mix." It has fibers in it and says to wait 28 days for max strengh. Motar mix is very light weight and soft in comparison. The small stones in concrete give it more mass and strenght. I fill up tennis balls.

There is still too much force from a sling, so unless you use a backstop netting and soft targets they will eventually chip and break.

I have pictures of them in the Gallery and some tips in a  posts about "concrete balls" several months ago.
