Ballistic Gel
Search:

When it comes to bullet penetration testing, the FBI is cited as the standard source of information. They use ballistic gel. If you want to buy some for yourself, I have scoured the internet for information about where you can get it.

The ballistic gel is made by Gelita (once known as Kind & Knox). They call it Pharmagel or "250 Type A Ordnance Gelatin".

Ballistic gel is prohibitively expensive. Sites that have cited prices have it range from $10-$14 a pound. The FBI is said to use 6x6x16 or 8x6x16 inch blocks. Each block is composed of 1 kilogram of ordnance gelatin powder (about 2.21 pounds) and 9 liters (about 2.37 gallons) of very hot distilled water. Mix well. Set in an area where it can not be contaminated for four to five hours and allow it to naturally cool to room temperature. Chill 48 hours in a sterile environment to a temperature of 4° C (39.2° F). The gel must remain at 5° C to be calibrated. You now have a 22 lb brick of expensive, tasteless gelatin. It is a 10% mixture (90% water, 10% gelatin powder).

It is said that one must purchase at least 25 lbs of the gelatin powder, which should make about 3.6 cubic feet.

A double batch can make a 6x10x18 brick, and a triple batch can make a 10x10x18 brick. You might want to coat your molds with some cooking spray so they pop out. If you forget, you could run hot water over the outside of the mold until it is able to slide out. The gelatin will spoil, so use it within a week. A few drops of wintergreen oil will help keep it fresh, and you never should freeze the gelatin.

The acceptable measure of a block of gelatin is a .177-caliber ground steel BB to penetrate 3.34 inches (8.5 cm) when launched at 590 fps.

The advantage of using this mixture is that you have the closest resemblance to human flesh that the FBI has found (without actually shooting someone). Also, when you shoot it, you can see the soft tissue damage as well as the track of the bullet. The downside is that it is expensive and you only get one shot per block.
