Ballistic studies

Dr A

Gidday Gents,

I am a researcher in AUT, Auckland and we are working on 3D printed bullets for veterinary/wildlife applications.

These are plastic bullets with various designs and calibres. We are biomedical scientists and not ballistic experts.

I wonder if you know a place or someone who can scientifically test accuracy, speed, impact force, wounding etc of our bullets.

Any ideas are welcomed.

Cheers
Dr A

Hi Dr A.
Plastic bullets??? There maybe a neche application but I can't see a reason why. I'm happy to be educated though.

Re: Ballistic studies
These are not designed to kill but ballistic drug delivery devices

Re: Ballistic studies
Now your making sense. I can see where, trajectory whise, that would be a better system than the old hypodermic needle type. But tissue damage is the first thing that comes to my mind. I'm sure one of the guys on this site will help you.
Regards
Bob

Re: Ballistic studies
I personally never shoot for wounding myself, puncturing an animal with a plastic bullet I can't see how that would be beneficial at all, trauma, infections I'd talk to a vet

Ali. Contact Nathan. Isn't that what a tranquilizer guns made for.? Wont you just cause nasty infected wounds. The plastic projectiles will force hair mud and bacteria into the targeted species. I'm not a vet but it seems like a cruel way to treat an animal?

Re: Ballistic studies
Hi,

I might miss a whole lot of stuff but this can be kinda interesting… If the projectile is made from a material that will break up in a controlled manner on impact it it could be interesting. (Thinking a hard case carrying the needle and medication within, then on impact disintegrating.)

If I had to hazard a guess, transporting liquid may be difficult from a ballistic perspective, and obviously the actual material used to form the bullet. Fragile enough to not cause harm to the animal but strong enough to withstand the forces and heat of being fired.

Especially if fired from a conventional rifle, even downloaded that would have to withstand significant force. But very interesting though! May be slightly more forgiving on animals with a thick hide. All in all, seems theres a serious amount that would have to be taken into account if the animal is to be darted without any harm.

What would the intended range be?

But yes, like others mentioned think Nathan would be the one to answer this. Will definitely follow this though, very interesting..

Good luck!

Re: Ballistic studies
I have tranquilized hundreds of animals with the conventional darts and I think it is about time that someone invented an improved delivery system.

The issue with darts is that they are heavy and must be driven only just fast enough so as to not cause penetration that might enter the animal. There are quite a few loads of different strenghts designed to offer longer range but if you are darting wolves like I was, then your target area is extremely limited to prevent penetration and mortality. A light weight delivery system loaded with a do-it-all drug like Telasol or one of the many others, would be a great boon and would reduce the rainbow trajectory enhancing accuracy.

Much of our work involved shooting from a helicopter so that a decent trajectory was desired.

Good luck with your efforts Dr A.

Re: Ballistic studies
Just to add to the above, since my retirement in 2003 I have not kept abreast of any advances in the drug delivery systems currently available. Have you done this kind of background work, and if anything, were there improvements others have done?

Re: Ballistic studies
this is interesting....IF we arent dealing with a troll?????
and we already have a great sytem of delivering liquid to target incased in plastic...its called paintball
untill Dr A comes back with intended use we shooting in the dark

Re: Ballistic studies
Hi Ali, could you please make direct contact with me rather than using the forums.

Unless you are wanting to go public with this now and fully explain to people what you are doing, I suggest you keep matters private. Otherwise and as others have stated, it will only cause confusion.

Sorry Bryan, I understand this is a topic of interest for you.

No issue here Nathan, and I agree.

Yes but when Colin Murdoch invented tranquilizer darts there were no 3d printers around ;) We can prevent infection, thats not a problem

You are onto it Cor. I am not sure about range but gussing 50-100 m minimum?
