| anybody heard of such a thing ? |

Google is our friend
First link that comes up looks like a recipe to me |

That's funny stuff right there.

| For a gelatin to be "accurate" and produce reliable ballistics data, you have to use "the right" gelatin to start with. Gelatin is rated in "blooms" for rigidity, with a 250 bloom being the standard for ballistic gelatin. Knox gelatin won't really cut it. But if you can find a 250 bloom gelatin, the rest of the instructions you find on the web will work. |

In describing gelatine, manufacturers often refer to "bloom" strength. This is an industrial standard which "grades" or measures the strength of the gelatine. Essentially, it describes the relative "hardness" or "rigidity" of gelatine when cured. Higher "bloom" numbers correspond with stronger gelatines. Gelatine with a "bloom" of 300 can be obtained from most special effects suppliers, including Burman Industries, Inc. (www.Burmanfoam.com), The Monster Makers (www.Monstermakers.com), and others, and is considered to be the strongest for use in three-dimensional make-up effects. The Nabisco™ Food Service Company produces Knox(r) unflavored gelatine, which is readily available in the United States. An equivalent to Knox(r) in the United Kingdom is Davis(r) unflavored gelatine. Both brand names can be purchased from grocery stores, pharmacies or food service companies (in addition to its use as a nutritional supplement, it is also used in confectionery recipes - including those wonderfully molded gummy bears, fish and worms). Both Knox(r) and Davis(r) brand gelatines are believed to have a "bloom" strength between 200 and 225, and can be used during experimentation in three-dimensional gelatine effects. |

I just want to make some to see how different bullets react .> i.e. harnady v-max,winchester black talon and various barnes bullets in my collection tsx,dpx, ect. You can do that. ARFcom members Tatjana and Brouhaha have done so in the past (check the Archives of the Ammo Forum). Note for the results to mean anything you'll have to calibrate the gel with a BB, and you have to keep the gel at the proper temperture (if it get's too warm it's results will be skewed). IIRC www.FirearmsTactical.com has instructions on preparing, storing and calibrating ballistic gel. |

I have participated in a few 'jello" shoots. Candidly having seen a few shootings, the "jello" shoots are a good indicator if you are ever attacked by a jello creature! As an accurate engineering model that has been substantiated in a juried academic setting, what do you propose as an alternative? |
| There is a company here in IL that sells it. They make professional ballistics gel that a lot of le agencies use, but they also sell to the public. It is sort of pricey if you ask me. When I looked it up it was around $90 or so to make a mold. I cant recall the name of the company, but I know you can buy professional grade gelatin if you look for it. |

Here is a link to the company in Il I was talking about. It isnt as expensive as I remember. $90 for 3 molds.Ballistics Gel And it includes the molds and some other things as well. Not bad at all.I may order some.
I dont know. Perhaps a call to this company and they would allow non LE to purchase it. |
| Hey guys I have actually made that "gel" using the knox stuff. yeah i know its not real ballistics gel but it was pretty cool. I shot it with a BB gun first and it only went in a inch or 2 then I shot it with my 15-22 using CCI stingers and you could see how the bullet entered the gel and exploded the back side out. My friend who works for a gun range has the real ballistics gel im trying to get him to give me some would like to see what the 5.56 does to it |

Not bad at all.I may order some. I dont know. Perhaps a call to this company and they would allow non LE to purchase it. Vyse and Kind&Knox are the two "big" manufacturers. One of them has recently been bought by Gelita if I'm not mistaken. I'm pretty sure that the standard mold will not be sufficient for rifle bullets. Gelatin testing is expensive, but it is the ONLY way to correctly model penetration and expansion of bullets. |
