Cost me $24 to make it.
The commercial gel is way to expensive for me, so after testing a few recipes, this is what I came up with.
The ratio I use is 1oz of unflavored gelatin to 1 cup of water.
I go to Walmart and buy the box pack($4.00 per box), so 1box=8oz’s( 8oz=8cups of water).
I use a Rubbermaid tote(5 liter) which is 10” by 15”.
Add the gelatin to cool water, stirring while adding. Once mixed, set in the fridge for 8 hours, when it’s set, I melt it back down in hot water( set the mold in my tub of hot water).
This will remove air bubbles and clear it, set back in the fridge for another 8 hours and it’s ready to use. Once it’s been shot a few times, you just remelt it in hot water and set in the fridge again. So far I’ve reused mine 8 times and it’s still working fine.
I’m sure it’s very similar, but commercial made has a few more ingredients in it.
I use a tablespoon of Consan20 (available everywhere) in my mix and it stopped the mold.
Its just too big to keep in the fridge.
my fridge he would be in trouble plenty. I think part of the project should include building an ice chest.
Without calibrating or making direct comparisons, there is no way to know how similar or dissimilar it is.
I’ll shoot a bb at 4’ and see how far it penetrates, if it’s the 3.5”, it’ll be very close.
That is only if your BB is fired at 590 fps (+/- 30 fps). Calibration is only valid for that batch and must be repeated for every batch.
I am sure your right but i made it just for the fun of it and not necessarily a scientific experiment.

You ever get around to validating your gelatin with a BB? Kinda interested in seeing how your home-brewed gelatin fares.
Most Red Ryders are in 350fps range.
I’ll post pictures later today, I used my Crossman with 3 pumps(chrono’d at 600 FPS) and it went in 4”.
Like I said before, the gel is pretty close.
Even if it’s not FBI specs, finding out how different ammo acts, it’s just another tool.
Excellent. Looking forward to it.
4'' is just over the maximum specified validation depth of 3.94'', so what you have is pretty close to the standard.
Your correct, powdered.
I’ve bought bulk online before, better pricing, but the convenience of driving 10 minutes to the store makes it more practical.
It's not all that terribly expensive to test in ordnance gelatin. Larger bulk purchases will help to 'economize', but it is especially important to make sure that you get 250 Bloom strength. I've done quite a bit of work with it, but never really messed around with remelting blocks like the OP, but I might mess around with the technique that he uses since it seems to eliminate some of the difficulty that I'd envisioned in doing so.
The important thing is that after remelting that the ''new'' block must shear-validate correctly. If the remelted block meets that standard, then it is a valid medium.
The gelatin described is a good "hack" and I applaud the OP's imagination. If accuracy is needed just use a second block with a known caliber, bullet and velocity and make the comparison.
