Kind & Knox sells it, but I hear it's pretty expensive.
Here's a a home-recipe that I found a while ago. I've never made it myself
1 part pectin powder
1 part gelatin powder
3 parts boiling water
Mix in double boiler and stir untill disolved.
A few drops of oil of wintergreen as a preservative & prevent mold

What dimensions would you need to test .30-06 or .308 without loosing any fragments?

I have no idea, but I'm buying stock in the Knox Gelatin Company right now... thats gonna be a lot of jello!
Most rifle rounds, especially supersonic, will penetrate over five feet of ballistic gelatin with enough force to punch a hole in a 1/8" steel containing wall. If you want to test rifle rounds, start looking at layers of pine boards. You can find many comparisons of other ammunitions fired through stacks of 1" boards; it was the standard test for penetration before ballistics gel was developed. I'm not sure you're going to be practically able to make enough Jello to stop a rifle bullet and contain any and all fragments.

Thanks Liko...
What about dimensions forhandgun rds?
The reason I ask is because my younger brother has to participate in his Jr. High science fair, and he asked me to help him out a bit...I haven't read all of the specifics yet, but I was thinking about testing the ballistics of different bullet weights or HP, SP, etc.

9mm JHP generally penetrates between one and two feet (it must meet FBI specs which means it can never penetrate less then 12"). I think if you were to find or make a clear box that was 4'x2'x2' you would be able to catch most if not all handgun rounds and all fragments. Ballistics tanks for handguns are about 8'x4'x4' and that's water; real ballistics gel will slow the bullet down more.
http://www.frfrogspad.com/gelatin.htm has some good notes on making 10% gel. Remember you need to store it at the right temperature prior to shooting and take calibration data if you want it to be really worth something.
For a handgun and maybe .223 you could use a 6x6x16 block, for a rifle test you'd want it to be more like 14 x 8-10 x 20. You're getting into some pretty expensive and pretty heavy (60-100 pounds) of gelatin blocks here.
For a junior high project I think you coud just shoot a couple of handgun jhp's into water or a wet newspaper block and come up with something that would work for less hassle.
