A biodegradeable, vacuum sealed, water-filled projectile. There has to be no air in it. Biodegradeability is not necessary, however, but it is an
extra advantage as far as leaving no evidence.
Since H2O does not compress easily, the bullet should survive the G-forces of firing. With a biodegradeable
water bullet, you can put down a target with minimal effect on the environment. In other words, it would leave little to no evidence for CSI to analyze.
Good for 007, bad for us.

public:transportation - Are you sure? |

I think we've done ice bullets here somewhere (or was that CSI?) - which would be an easier way of delivering a deadly H2O bullet - or apparently would be if the ice wasn't liable to vaporisation due to the high temperatures involved in firing a bullet. |
|
| |
Which poses a problem for this idea - if you are going to have water in a biodegradable casing, that casing will have to withstand the pressure of the contents trying to turn to steam - no mean feat. |
|
| |
If you mean a sort of "bag" of water, it
wouldn't work. The propellant would just
blast a hole through the water. And even
if it started to travel down the barrel, the
drag forces on the sides would rip it to
shreds. |
|
| |
There are biodegradeable plastics that are pretty hard/strong. The "bag" would have to be rigid. |
|
| |
And yes, ice does not withstand the temps/g-forces of firing. You end up shooting snow 20 feet. |
|
| |
What does the water add to the equation? You have already posited a biodegradable material to contain the water, why not make the entire bullet out of that material? |
|
| |
I think the idea is that the water provides the weight required to impart suitable "stopping power" on impact. |
|
| |
The heavy biodegradable casing wont biodegrade in time for someone to ponder on the perfect crime, leaving you with a bullet, containing water - which I suppose might be cheaper (and more environmentally friendly?) than a regular bullet, but other than that (and that's already stretching it) I don't really see any advantage. |
|
| |
I don't think this will work, but the outdoor shooting range will be a greener place. |
|
| |
The casing screws this idea. The good old ice bullet is better. One could fire them with Colonel Moran's air rifle to avoid the heat. |
|
| |
here is a biodegradable casing full of bones. Oh, wait, I guess you are one already! |
|
| |
As far as leaving no evidence, why not a blood bullet? Fill it with any random person's blood, stolen from a blood donation center and go shoot someone. |
|
| |
hmm could water be used as a second stage propellant ? gunpowder flares turning water into steam, etc. |
|
| |
But what about using CO2 to power the shot - this would keep the charge cold and propell the ice bullet with some force... doubt you could take a shot at much more than a few yards - the bullet might melt in flight - a 1000 yard shot would be a no go for sure... |
