You know, I believe that the Romans once attempted putting sharpened iron dowels through some of their Glandes in Spain, so that the points of iron formed the points of the glandes. A lot of them bearing the name of Pompey.

Now, that sounds like something that is just downright mean...

I have a feeling if you aren't wearing anything substantial... on a point-on impact... I think those would have the habit of  going right through you!

Given we have advanced metallurgy I think a tungsten based alloy is likely the best material for a super devastating glande.

Yep, Tungsten glandes would be awesome. Or Depleted Uranium ones... but then the Military would probably give you the evil eyes.

Oh, What I would do for Iridium or Osmium glandes. The Densest elements around, but also very rare on Earth. Cry

Quick, we need to get to space so that we can mine the asteroids for that stuff!

Yeah I think tungsten is about as far as we need to go before it becomes hazardous to the slinger, it is hypothetically hunting  so I’m assuming we want to keep the meat

  Of course the obvious concern with tungsten is that it's more expensive than lead and lead isn't cheap.  But it would probably be your most effective ammo within reason.

Also much more difficult and expensive to shape

Definitely harder to shape and more expensive but given that it will likely retain its shape when hitting things it could be more economical in th long run, well as long as you didn’t lose them.

I actually have a small amount of tungsten bar that I have used for slinging

Would be easier to mold lead around tungsten rod and put pointy tungsten fishing weights at both ends of the rod for max penetration and to get a nice shape for the pouch and even better aerodynamics. Wink

I can't exactly sling lead as consistently as stone and I lose it easily. I would be devastated if I lost such an expensive and difficult to make projectile.

P.S.: can we get a picture of the tungsten bar?

Here is some pics

As you can hopefully see it is very small for the weight

The 75g piece of tungsten gives a good perspective on how small a glande shape would be , likely this much material shaped correctly into a sharp point on either end would be a little larger in diameter but relatively similar in other dimensions. This would (I suspect) be a very good penetrating glande.

The tungsten May be tungsten carbide. And if so an even smaller glande would be possible.

I have thrown some and they really hold their momentum, I can only imagine how a better aerodynamically shaped glande would perform.

As for tungsten fishing weights
These 2oz miller punching weights look like they were made for us

From what I could find, I think the best shape to use for such a glande would be a teardrop shape with ~3:1 length-width ratio, a parabolic nose and a conical tail. This is supposedly the most aerodynamic shape at subsonic speeds, as it helps maintain laminar flow of the air over the object better than any other (If I understand the physics correctly). - That's also why subsonic aircraft have blunt noses.
For supersonic speeds it would probably be the sears-hack body, but you would need the strength of Zeus to throw that fast!

I would agree for a glande that is not intended for hunting.
But for hunting I suspect that a sharp point would be an advantage on a penetrating projectile. perhaps a teardrop shape is the best if blunt trauma is the goal.
This would reopen the “blunt vs penetrating” discussion.
And many factors would have to be considered.
Accuracy, game animal, projectile speeds, projectile weight, just to name a few.
I think if blunt force is the goal using a material such as tungsten would be a disadvantage.

tear drop shape is the best option for external ballistics but not for internal and terminal. Spiral throw gets even more difficult if the projectile is asymmetrical unless it self stabilises during flight.

those miller punching weights look like the next record holder ammo . A suitable sling design is probably necessary for slinging it though. also they are probably lost once they are hurled... we need either a tiny gps withstanding impacts and being detectable below ground or an extremely accurate slinger at 600+m.

At around $15USD each you are literally throwing money away ha ha  Grin

Speaking of records what are the official numbers??

Sarosh- tear drop shape self stabilizes I believe.

As for best ammo, why not something with an exploding on impact?
That would really ruin the catch but as an ammo concept its neat.
