Ballistic gel is an essential tool for analyzing the spread and effect of bullets. It simulates human or animal tissue and is used to test ammunition for hunting, self-defense, and sport. The correct preparation and handling of the gel are crucial for obtaining precise results.
Key Points:
- Preparation: 125 g of gelatin powder per 1 liter of water, test at 17–23 °C.
- Testing Procedure: Shoot gel blocks, measure the depth and expansion of the bullet.
- Application: Valuable for hunters, shooters, and ammunition manufacturers.
- Equipment: Gunfinder offers suitable products like gel molds, measuring devices, and ammunition.
The tests help assess the performance of bullets, whether for hunting, sport, or research.
Making Ballistic Gel for Tests
Stuff and Tools You Need
To make good ballistic gel, use high-bloom gelatin. Gelatin powder with a bloom value of 200 is good, as it creates firm and realistic gel for testing. Use distilled water to avoid any impurities.
You will need:
- A large pot or bowl
- A whisk or mixer
- A water bath or double boiler
- A digital thermometer to monitor the heat accurately
- Rectangular containers made of plastic or metal, which you should grease with oil beforehand
To find everything you need – from gelatin powder to test ammunition – check Gunfinder. It helps hunters and shooters find everything in one place, and often there are free listings. Once you have everything, you can start mixing the gel and letting it set.
How to Make the Gel and Let It Set
The mixing ratio is important for real test results. A good rule is: 125 g of gelatin powder per 1 liter of water. This makes the density correct, just like real tissue.
| Mixing Ratio | Gelatin (g) | Water (l) | Bloom Value | Note |
|---|---|---|---|---|
| 125:1 | 125 | 1 | 200 | Commonly used ratio |
When you have everything ready, do this:
- Weigh the gelatin: Check if you have enough gelatin.
- Add gelatin to the water: Slowly sprinkle the powder into cold water while stirring continuously to avoid lumps.
- Let it bloom: Wait 30 to 60 minutes until the gelatin is completely dissolved.
- Heat and stir: Heat the mixture in a water bath to 30–40 °C. Stir often until it is clear.
- Pour into molds: Pour the clear mixture into the prepared molds.
Afterward, let the gel set in the refrigerator for 4 to 6 hours. After this time, it should be firm and slightly elastic – perfect for your tests!
How to Test Bullet Expansion
Preparing the Test Area
A well-prepared test area is important for good results. Place the gel block on a solid, flat surface. Use a mat to keep everything level. The temperature must be between 17 and 23 degrees for the gel to remain stable. Maintain a distance of five meters for shooting to preserve speed and achieve consistent results – tests have shown this.
Ensure that there is a safe backstop behind the gel that can effectively catch bullets. Mark everything as a danger zone and do not allow unauthorized persons to enter. Once everything is ready, the test can begin.
Shooting into the Gel
Record all important data, such as distance, angle, type of ammunition, and environment – this is important for later. Aim well at the center of the gel, as this is the only way to ensure clear results.
Wait briefly after the shot, as the gel may still be moving. Then take photos of the entry point and the wound channel from multiple angles to document the test accurately. Always observe safety rules during this process.
Legal and Safety Rules
In Germany, shooting outside of approved shooting ranges is not allowed without permission. Conduct your tests only in authorized areas. Always wear safety glasses and hearing protection, and keep unauthorized persons away.
Your weapon must be legal, and the ammunition must be stored and transported correctly. For public tests, you may need additional permits. Always point the weapon safely and stay away from the trigger until you are ready to shoot – safety first.

Measuring and Evaluating the Data
Taking Important Data Correctly
To measure the depth, use a ruler or a digital caliper. Place the tool against the gel block and measure the distance from the surface of the gel to the end of the bullet. You can find the size of the bullet by removing it from the gel and measuring the thickest part with a caliper. For even better numbers, you can use programs like “k-analyzer.” These programs analyze images of the gel block and accurately measure the length and width when a scale is present in the image. Another important point: The temperature of the gel, which should be between 17 and 23 °C, as it significantly affects the data. Be careful not to have hits at the edge of the gel block, as they can skew the results. With these precise measurements, you can document your results well.
Recording and Comparing Data
Once you have all the data, you should write it down clearly. A simple data sheet helps with this. Write down the type of ammunition, caliber, test conditions, depth, and diameter of the expansion. Include photos of the gel block and the bullet. Important: The photos should always have a scale to make future comparisons easy. For example: A 9 mm Luger with 124 gr JHP showed a depth of 32 cm and a bullet expansion of 15.2 mm. You can compare these values with the manufacturer's specifications and standards to assess the quality of the ammunition.
Understanding the Results Correctly
The measurement data is necessary to see the power of the ammunition realistically. The depth indicates whether the bullet hits vital organs when hunting or meets the necessary standards for self-defense. The expansion of the bullet changes the size of the channel and thus the stopping power. In hunting, it is important that the bullet penetrates deeply enough to hit vital organs but does not expand too much to pass through without utilizing its energy. In sport shooting, consistent expansion and predictable depth are important. Ammunition that expands well and falls within a typical range for self-defense often meets FBI standards.
With Gunfinder, you can search for ammunition that fits your tests. The site has plenty of information and user reviews that help you find the right ammunition for real gel tests.
Common Problems and Solutions
Common Mistakes and How to Prevent Them
Typical Mistakes in Testing
Pack the gel blocks tightly without gaps so that the channel is complete. If there are gaps, the channel is broken. This makes it difficult to measure accurately. A simple trick: Place thin cardboard strips under the entry point to eliminate gaps.
Uneven temperatures can lead to incorrect results. Always keep the temperature between 17 and 23 °C. Only then can good results be obtained, especially in tests with the same ammunition.
Without good photos of the tests, even good tests are useless. Ensure everything is clearly visible, and take photos of the entire channel in good lighting. A poorly placed scale will make all measurements incorrect.
Avoid these mistakes, and your results will be much better.
How to Get Better Results
Take photos of the gel blocks from different angles to see everything clearly. Take pictures of both long sides and ensure the camera is straight to the channel. Angled photos can lead to incorrect measurements.
Carefully record the data to avoid measurement errors and make good comparisons possible. Write everything down – type of ammunition, weight, bullet design, velocity, gel batch number, temperature, and distance – in an accurate data sheet.
If you use the k-analyzer software for analysis, set the measurement points accurately: the lowest point at the bottom, the highest at the top – and in a straight line.
| Problem | Cause | Solution |
|---|---|---|
| Incomplete channel | Gap between gel blocks | Place cardboard strips at the starting zone |
| Results vary greatly | Temperature fluctuates | Always keep the temperature at 17–23 °C |
| Measurements not accurate | Scale not straight | Align the scale accurately |
With these tips, you can achieve good test results and easily compare them with others.
Examples of Test Results
Here you can see how theory works well in practice. If you avoid the mistakes mentioned above, the tests will show clear differences between best performance and problems.
Round bullets behave differently than shaped projectiles. At high speeds, round bullets penetrate deeper into the gel, as the high fat content in the gel creates less friction. Thus, they "slide" at the end of their path, which can increase depth.
Too much penetration occurs when the bullet passes through the gel block without expanding enough. Too little penetration happens when it does not go deep enough. Optimal width is when the bullet penetrates deeply enough and expands well.
The shape of the gel block should only extend 1-2 cm outward. If the shape is more, it may indicate problems in gel preparation or too much energy upon impact.

FAQs
Why is the temperature of the gel so important for tests?
The temperature of the gel is very important because it significantly affects the softness and thus how realistically it mimics body tissue. If the gel is too warm or too cold, the test results will not be accurate, as the bullet will behave differently than in normal tests.
To achieve good and accurate results, the gel must be cooled to about 4 °C. This is the temperature that experts say is best. This way, the results are realistic and consistent.
What rules are important when testing ammunition with ballistic gel?
When testing ammunition with ballistic gel, safety must always come first. Here are a few simple rules you should always keep in mind:
- Safe testing area: Conduct your tests only in a safe area where unauthorized access is not possible. This keeps everything secure.
- Wear protective clothing: Always wear hearing protection and safety glasses to protect yourself.
- Caution when using: Always adhere to safety rules and be very careful with the weapon and ammunition.
- Proper aiming: Ensure that the weapon is always pointed at a safe target to avoid dangerous ricochets.
These steps help create a safe testing area and minimize hazards. Safety should never play a minor role in these tests!
