Making/Testing Ballistics gel for Air Guns

Ok guys, 1st off, i have to say that in no way shape or form do i consider this REAL Ballistics Gelatine.  Ive never seen nor handled the real stuff so, i truly don't know how close in density and elasticity this stuff comes to the real thing.  I got the recipe from YOUTUBE.....of course!....lol.

Also:  THIS IS NOT JELLO BRAND GELATIN.  THIS IS GENERIC or PLAIN GELATIN.  This stuff is more dense and tougher.

Anyways, i have to say though, not only was this project very fun and entertaining but i learned a couple of things.  1st is, how to reheat (low fire/temperature on the stove instead of medium or high) this stuff to keep it clearer longer and to not use Pam or cooking oil as a release agent.  I simply NOW put it in a container of choice for the shape with no release agent and slowly peel the top edges away from the container all the way around and VOILA!.  Seems to stay clearer longer than when you add oils as instructed on You Tube as a release agent.  2nd, using this recipe only cost whatever your store charges for 8oz of gelatin.  Mine only cost 5.98 plus tax.  So it's cheaper than the real thing and easy to handle and mix and cure.  3rd, the mixture is STRONG ENOUGH TO STOP A 50 FPE JSB KING in ONLY 13" from a mere 30 feet away!  But of course, always use a GOOD BACKSTOP!

Guns used in test:  Rapid .25 and Cros Mods Disco .22

Pellets tested:
.22 cal JSB Exact-15.9 gr @ 908 fps/29.1 FPE
.22 cal Predator-16.0 gr @ 916 fps/29.8 FPE
.25 cal JSB Kings-25.4 gr @ 940 fps/49.8 FPE
.25 cal Predator-26 gr @ 946.8 fps/51.7 FPE

The results from all the pellets were as expected.  I knew the Predators would drop the poly-tip and then expand pretty good and i knew the Exacts and Kings would penetrate like the dickens.  Actual hunting time in the field has shown me this.  I find poly-tips in animals and a lot of bruised tissue while with the Exacts and Kings, well, I've never found one inside of quarry..lol.  What i did not expect was for the gelatin to actually stop the Kings and Exacts in 12-13" of penetration.  This stuff works better than i thought it would.  Especially that i was only about 30 feet away.  I also did not expect to actually capture the wound channel along with the SPIRALING EFFECT.  And the gelatin showed exactly what DOES happen when it hits flesh, the domes create a much narrower wound channel and penetrate further than the HP pellets.  The Predators also mushroomed perfectly and tracked very straight as i traveled inside the gelatin.  Again, I've never seen a Predator hit in one place then come out somewhere totally opposite from the entrance.

FYI:  Please forgive the 25 cal test which was the first in the video to be done but the gelatine came out darker (more orange) cause of the repeated use of oils as a release agent and high remelting temps.  But you can still see the pellet travel through the gelatin.  The .22 cal testing portion of the video came out a lot better as i bought more gelatin and rethought the process and rethought the filming.  So excuse that as it was all trial and error (1st time) caught on video...lol.  But for the next video, i will use the OVERHEAD video technique as well as smarter lighting like in the .22 portion (used a clear plastic box lid with a halogen light underneath to illuminate).  BTW, ILLUMINATING (lighting) is the most important part of filming to get good footage for those of you that wanna try this and film it for yourselves.

Enough of my yappin...............................................
