What Is Ballistic Gel and What Is It Used For?
What is ballistic gel?
Ballistic gel is a specialist testing material designed to simulate the density and resistance of soft tissue during controlled testing. It is widely used to help visualise how projectiles, fragments, tools or other objects behave when they pass through a soft medium.
The material is commonly used in forensic, law enforcement, military, research, medical and product testing environments. It allows users to observe penetration depth, wound path, expansion, fragmentation and energy transfer in a clear and repeatable way.
At Defensible Ballistics, our ballistic gel products are designed for professional, educational and testing applications where consistency, clarity and reliability are important.
Why is ballistic gel used?
Ballistic gel is used because it gives testers a practical way to see what happens during an impact. Rather than relying only on theory or external damage, gel allows the path of travel to be inspected after the test.
Depending on the type of gel used, it can help show:
How far an object penetrates
The shape and direction of the wound path
Whether a projectile expands, deforms or fragments
How energy is transferred into the surrounding medium
How different test items compare under similar conditions
This makes ballistic gel useful for demonstrations, product development, training and research.
What is ballistic gel made for?
Ballistic gel is not limited to one type of user. It can be used across a wide range of sectors, including:
Forensic testing
In forensic and investigative settings, ballistic gel can be used to help demonstrate impact behaviour and wound path characteristics. It gives a visual reference that can support controlled testing and comparison work.
Law enforcement and military testing
Ballistic gel is often used to test and compare ammunition, protective equipment and other operational materials. It can help demonstrate penetration, expansion and energy transfer in a consistent test medium.
Airgun and hobby testing
For airgun users and enthusiasts, ballistic gel provides a useful way to compare pellets, slugs and other projectiles. It allows users to see penetration depth and deformation in a more informative way than simply shooting into a hard target.
Medical and research applications
Ballistic gel materials can also be used outside traditional ballistics. In medical, academic and research environments, gel can be used to create training models, imaging phantoms and soft-tissue simulation products.
This makes ballistic gel useful for more than projectile testing alone. It can also support education, product development and controlled demonstrations.
Synthetic ballistic gel
Synthetic ballistic gel is a reusable transparent gel supplied in calibrated densities. It can be used out of the bag, melted, cast into moulds and reused multiple times while retaining its calibration when handled correctly.
At Defensible Ballistics, synthetic ballistic gel is available in different formats, including blocks and chips.
Synthetic gel is a good option when users want:
A transparent testing medium
Reusability
Consistent calibration
The ability to melt and recast the material
A practical solution for repeated testing
Synthetic ballistic gel is particularly useful for customers who want a long-term testing medium that can be reused after testing.

Synthetic Ballistic Gel Chips
Natural ballistic gel
Natural ballistic gel is a traditional gelatine-based testing material. It is commonly associated with forensic-style testing and requires preparation before use.
Natural gel is generally supplied as a powder and mixed with water before being heated, poured and set. Once prepared correctly, it provides a soft testing medium suitable for controlled demonstrations and testing.
Natural ballistic gel is a good option for customers who want:
A traditional gelatine testing medium
10% forensic-style gel preparation
A material suitable for controlled testing
A cost-effective gelatine-based option
Ballistic soap
Ballistic soap is another specialist testing medium, but it behaves differently from ballistic gel. It is used when the aim is to preserve the temporary cavity or impact path more permanently.
Unlike gel, which can close back around a wound path, ballistic soap can hold the cavity shape after impact. This makes it useful for analysis, photography, demonstrations and situations where the wound path needs to be examined after the test.
Ballistic soap is useful when customers want:
A more permanent visual record
Clear cavity preservation
A solid analytical testing medium
A product suitable for demonstrations and comparison work
What density of ballistic gel do you need?
Different tests may require different gel densities. Defensible Ballistics supplies synthetic ballistic gel in calibrated options including 10% forensic/FBI-style density and 20% NATO-style density.
As a simple guide:
10% ballistic gel is commonly used as a forensic-style soft tissue simulant and is often chosen for general testing, airgun testing, demonstration work and comparison testing.
20% ballistic gel is firmer and is commonly associated with NATO-style testing. It may be chosen where a denser medium is required.
Choosing between 10% and 20% depends on the purpose of the test, the level of resistance required and the type of result the user wants to observe.
Ballistic gel blocks vs ballistic gel chips
Ballistic gel can be supplied in different forms.
Pre-made blocks are convenient because they are ready to use and provide a simple testing format. They are ideal when customers want a prepared product with minimal setup.
Gel chips are designed to be melted and cast into a mould. They are useful when customers want to create their own block size or shape, refill a mould, or cast the material into a custom testing form.
Both formats have their place. Blocks are simple and convenient, while chips offer more flexibility.
Why use a mould?
A mould allows melted gel to be cast into a consistent shape and size. This is useful when repeatability matters or when a customer wants to create standardised blocks for testing.
Defensible Ballistics supplies steel moulds in a range of sizes to support different block formats. Using a suitable mould helps produce cleaner, more consistent test blocks and makes preparation easier.
Is ballistic gel reusable?
Some ballistic gel products are reusable, while others are not.
Synthetic ballistic gel can be melted and reused multiple times when handled correctly. This makes it a practical choice for customers carrying out repeated testing.
Natural ballistic gel is generally treated as a prepared gelatine product and is less suitable for repeated remelting and reuse in the same way.
Ballistic soap is used differently again, as it is designed to preserve the cavity or impact path for inspection.
What should you consider before buying ballistic gel?
Before choosing a ballistic gel product, it is worth thinking about:
What you are testing
Whether you need a transparent medium
Whether you need the gel to be reusable
Whether you need 10% or 20% density
Whether you want a ready-made block or chips for casting
Whether you need a mould
Whether ballistic soap would be better for preserving the cavity
The right product depends on the purpose of the test and the result you need to observe.
Summary
Ballistic gel is a specialist testing material used to simulate soft tissue in controlled testing environments. It helps users observe penetration, wound path, energy transfer and projectile behaviour.
Synthetic ballistic gel is a reusable transparent option that can be melted and recast. Natural ballistic gel is a traditional gelatine-based material. Ballistic soap is used when the cavity or wound path needs to be preserved more clearly after impact.
For customers carrying out forensic, law enforcement, military, airgun, research or medical testing, ballistic gel provides a practical and visual way to understand impact behaviour.
