Ballistic Gel Powder 2 lbs – Calibrated Gelatin Mix for Blocks, Targets and Dummys for Shooting - For Health Science, Education and Projectile Analysis – By Fit Lane Nutrition

Great stuff! I used the better part of two bags to make three blocks, using small totes as molds. I didn't notice any bad smell when I was mixing it and it was very easy to follow the instructions. You can see the clarity in my pictures, and it was very easy to see the wound channel and the rounds in the block. 100% recommend this stuff if you are looking at testing bullets

Works very well

I got this for a reference block for testing. I made up a small 20% NATO block, weighing the powder and measuring the water volumetrically using the instructions on the packet. In particular I was careful to make sure the water measured 140°F after being poured into the mixing bowl. I mixed it using a stand mixer, pouring in the powder slowly, then finished mixing with a silicone spatula. Finally I poured it into silicone molds, left uncovered for 6 hours and refrigerated for about 30 hours. It recommends 36 but it seemed like it was ready. I then tested it using FBI calibration protocol: firing a .177 steel BB into it at 590fps +/- 15fps, velocities confirmed using a Garmin Xero 1 radar chronometer. I used a Barra Cowboy multi–pump air rifle and Crosman copper–plated steel BBs. Measured velocities with 5 pumps were frequently within 1-2fps of 590fps, occasionally as low as 580fps but within the test range. I found that BBs would penetrate approximately 37mm into the blocks at this strength; it’s supposed to go 2” into the 10% mix I think, so this may be within spec for 20%. This may be why the FBI uses 10% gel, even though 20% is more representative of flesh; it’s much cheaper and doesn’t make the tracks exceedingly longer. I may repeat this using a 10% mix to see if I can get a result matching the FBI spec. From the color of other pictures of this stuff, I had worried that it would not be clear enough to be able to see the track well. Thankfully this was not the case, and the top surface of the block was perfectly transparent, except for a small area that had some froth I had failed to skim out. Not bad for a first attempt, though! Note that the block in the picture is only 1 cup’s worth of water, and 2oz of powder by weight. In the picture there are also some much shorter tracks that were left by a small CO2 BB gun I thought I’d test for comparison. Funnily enough, it measured as much as 446fps, but the penetration into the block was far less than the 590fps BBs. At $50 or so, this should be substantially cheaper than buying blocks online, and the amount of work wasn’t bad with a stand mixer and a sous vide thermostat heater. I recommend giving it a try! Next I’ll make up some 10% blocks & see how it compares!

Works great for catching bullets . I used 2 one gallon Crystal Geyser water jugs for molds and layer them on the side . It caught 7.62x39 , 5.56 .

Wish there was more for the price e
