Perma-Gel Ballistic Gel Block 17-1/2 x 11-1/2" x 5"
Technical Information: Perma-Gel Ballistic Gel
Perma-Gel (from the manufacturer):
Perma-Gel is a synthetic, clear, non-toxic "soft tissue" medium for the testing and comparison of different types of projectiles and loads, which is conveniently recyclable by a simple melting process. In developing this product, Perma-Gel has kept two main objectives in mind:
- To provide hunters, shooters, hand loaders and ballisticians with a room-temperature ballistic medium that closely simulates cold (4° C) 10% ordnance gelatin without its inherent decomposition problems.
- To provide the user with the ability to re-melt/reuse the medium by simply using a 110-volt appliance (available as part of a kit).
In limited testing, Perma-Gel has found that trajectory, deformation and permanent wound cavities created by expanding, high-velocity (i.e., above about 1600 fps) bullets are very similar to those created in gelatin.
Using Perma-Gel to evaluate low-velocity (i.e., less than 1600 fps) bullets will show somewhat lesser degrees of bullet expansion than in gelatin, and studying non-expanding ("Full Metal Jacket") bullets will show greater penetration. lthough "temporary" cavities are not normally studied by individual shooters, the professional ballistician will find that high-speed photography will record remarkable views of temporary cavities, owing to the superior clarity of Perma-Gel.
