I have a challenge for you guys: get the material cost of your ammo down below $0.10 per piece

I think that is impossible unless you are selling 10gram bullets or something

My land has a ton of clay. I COULD just shovel it up, and roll it on the mokds. Then dry it out.

But i am lazy. I might do that one day

I specifically said “material cost” which excludes labor. If you’re making ammo in bulk, I think it’s very possible, but not if you assume that it isn’t before trying.

Impossible isnt the word i would use. Easy is more like it.

...

Less than 2 cents per 4 oz shot. Extremely durable and almost as dense as a river stone. Perfect shape etc. Also anyone has access to it. Hard to beat

Not being sarcastic here Sarosh.... but wouldnt that be less than 10 cents per shot? Im too tired to figure out where my brain is going wrong here.

Sure. We can go with 0.10€ if you want. That leaves a lot of room for fiber or chemical additives to achieve different properties.

I’m just trying to eliminate some of the “gold plated” options like machined tungsten.

I meant more than I wrote. Yes that is 0.0034€ per shot which means the challenge Nooc proposed has been accomplished. In reply #91 I thought he was talking about price including labour. Clearly he isnt. My bad, I didnt read the material in material cost Tongue

I see. So ya you are right though. Its the labor cost that is the real problem. Actually material in slinging is super cheap. Its labor in gathering, making and regathering shots that is the real cost. Which is why im so big on backstops. Because even 2 cent concrete ammo isnt a viable solution if you only get a couple shots from each.

What I really would like though is a moldable epoxy putty that I could use in CAs rollers. But that stuff is so much more expensive than normal clay or concrete. Sooo much more convenient though.

People are now 3D printing concrete houses using a small crew. If you can do that, you can also automate the mixing and pouring of cement into glande molds. It’s a solvable problem at scale.

Ive dreamed about something like that for years. If the material is cost effective that might be the beat solution

It’s conceptually simple, but the devil’s in the details. There’s a lot of design that must go into the mold, the cement formulation, mold release agents, automated mixing, pumping, and material handling.

The ideal solution would be an ammunition “factory” that is easy to replicate around the world. Local production is preferred because the shipping costs for the final product would be fairly expensive.

If you really want to get fancy, add fibers under tension to make pre-stressed concrete ammo

There’s also going to be some secret sauce in the curing process.
