First video launched – review of Bullistic gels

One thing I’ve noticed in using, reviewing, and reading about various rounds of ammo is — a lot of people don’t have any idea how well their bullets actually perform.  For most of us, we pretty much have to take the manufacturer’s word, or pick based on what’s new and fancy or what has a pretty package or the biggest ad in the magazine, or what the bloggers are writing about.

Is that sane? I mean, if you’re carrying a firearm or have one in your home for self defense purposes, you’re pretty much betting your life that the rounds you’ve chosen are going to get the job done, aren’t you?  And since that’s the case, it’d be nice to know how those rounds really perform, from your particular gun…

… which leads us to the whole realm of bullet testing and ballistics gelatin.  There are lots of ammo tests on YouTube, but I’ve been pretty shocked by just how unscientific and, well, let me just say it — random and unreliable many of them are.  There are a few people who seem to know what they’re doing, but for every one of them, there’s a hundred people out there shooting water jugs, or newspaper, or mixing up food-grade jello and shooting that, and they’re doing so in such an uncontrolled and unscientific way that the results they’re getting are … well, they’re maybe entertaining, but they’re far from accurate and definitive.

I plan on doing a lot of ammo testing here at Shooting The Bull, and as far as I’m concerned, if the results aren’t accurate, repeatable, and reliable, then there’s no point in publishing them.  I don’t plan on shooting a plate of jello and claiming that it’s going to be the same as ballistics gel!  When something’s as unpredictable as bullets are, nobody can ever claim that their testing results are absolutely definitive, but — I think we can do a lot better than shooting into a water jug.

Ballistic Gelatin

So how DO you test ammo to see how it performs?  The standard is genuine 10% ordnance gelatin, otherwise known as “ballistic gel”.  It’s consistent, it emulates the density of muscle tissue, and it has been correlated against actual bullet wounds in people and in animals to show that it is, indeed accurate.  Which is fine and dandy, but how does that help you? Because ordnance gelatin is not exactly something you have in your cupboard, you don’t pop down to the Wal-Mart and pick up a block of ordnance gelatin, and even if you were to buy some (from these guys) then you still have a lot of work in front of you — you have to properly prepare it, you have to properly cool it, you have to properly store it, and you have to properly shoot it.  It’s no picnic, especially because, well, I guess you could eat it at a picnic, but I wouldn’t recommend it, as it’s basically boiled up pig skin and ligaments and tendons and all that nasty stuff.  And once you’re done shooting it, you really want to get it examined and discarded as soon as possible because the longer it sits there, the nastier it gets.  It’s basically boiled up meat products, and it’ll start to rot and stink like rotting meat after a little while.

But, if you manage to buy the right stuff, and mix it properly, and refrigerate it for two or three days so it gels properly, and you can keep it at no more than 41 degrees, and you manage to shoot it within less than 20 minutes of pulling it from the refrigerator, and you manage to shoot a steel BB into it at 590 feet per second and the BB penetrates between 2.95 to 3.74″, no more, no less (these are all the steps you need to take to make sure the gel is actually usable), then you can get excellent results.  And if you mess up on any of these steps?  If you buy Knox gelatin from the grocery store, or you heat the water too hot, or you don’t dissolve the gelatin perfectly (takes about 20 minutes of constant stirring, trickling the powder into the water slowly and methodically), then your block won’t be any good and your results will be useless.  Or if you don’t store it properly, in a refrigerator set for 39 degrees, for at least 36 hours, it won’t set properly, and again won’t be useful.  And if you leave it in the sun or take too long to shoot it (so that the core temperature rises above 41 degrees in the block) then it won’t calibrate properly, again rendering your results useless.  Oh, and did I point out that these blocks cost around $42 each to make, and can only be used once?

So, yeah, real ordnance gelatin is not really for the hobbyist.  It’s too expensive to do on an ongoing basis, and it’s too much work with too many “gotchas” if you mess up any of the steps.  It’d be profoundly disheartening to spend the money, the time to make it, the time to cool it, find a way to safely and properly transport the gelatin to a shooting range, and then find out that when you shoot a BB into it you get the wrong results!  Then you have to throw the block away and start over.  (Note, there is a formula that can be used to rescue you in such a situation, in Duncan Macpherson’s book “Bullet Penetration”, but the book’s out of print, the author’s deceased, and the only way to buy it now is used, and my copy cost over $80 so … there’s no easy way out of that mess).

Common Alternatives

With so much precision necessary, is it any wonder that people have turned to alternatives? Water jugs, “wet pack” newspaper, or Knox unflavored gelatin are three of the most common, but they’re all, for various reasons, just bad ideas.  The water jugs, well, I’ll leave that for another article, I’ve got lots to say about that, but let me just say that I think water jugs are a terrible way to test ammo.   Popular, certainly, but still a lousy, inaccurate, deceptive, misleading way to do it. Wet pack newspaper is better, but it still isn’t reliable, or accurate, and doesn’t give controlled results.  And Knox gelatin… that’s just kind of silly, because while it is in the same family as ordnance gelatin, it by very definition ISN’T ordnance gelatin.  If it was, it’d have been sold to the ordnance gel industry; gelatin that fails to qualify for ordnance gel specifications gets sold to the food industry, so, by very virtue of it being sold as food, you know it isn’t real ordnance gelatin.  It doesn’t meet the standards.  That said, if you had to go with a homemade solution, you could come closer to accurate by using the Knox stuff than by using water jugs or wetpack, but … why bother?  To get the most accurate results you’ll have to go through all the same work, all the same effort, all the same storage and temperature requirements, and … here’s the kicker … if you’re buying enough Knox gelatin to make a 20-pound block (you’d need 32 ounces of gelatin powder to make one 20-lb block) then… it’ll cost you just about as much as ordnance gelatin would!  So why not buy the real stuff instead of using some homemade grocery store substitute?

Viable Ballistic Gelatin Alternatives

So what’s a person to do?  If you can’t afford, or don’t want to deal with, ordnance gelatin, what are the real and useful alternatives? There are two.  One, shooting real water (NOT water jugs!), is a true no-cost way to go, and can, when done properly, yield real world results.  I will be doing a complete article and video on how to use water for real ammunition testing; for those who don’t want to wait for the article and want to start exploring it now, you can get Duncan MacPherson’s book “Bullet Penetration” or Charles Schwartz’s book “Quantitative Ammunition Selection”.

The other option, and one that I find very appealing, is to use one of the new synthetic ballistic gel substitutes on the market, such as the clear ballistic gel from www.ClearBallistics.com.  This product has been introduced to the market within the last year, and it presents itself as a comparable substitute to genuine, organic 10% ordnance gelatin.  That’s really interesting to me, because — as a synthetic, it should be immune to most of the problems I have with using regular ballistic gel: it doesn’t need to be refrigerated, it doesn’t rot, it doesn’t require being at a specific temperature, and, perhaps most significantly to the independent ammo tester, the gel blocks can be reused!  You can re-melt and reform them multiple times, which really brings down the cost-per-block cost.  They’re initially more expensive than a block of ordnance gelatin would be (today’s pricing looks to be $129.99 for an “FBI Block”) but if you re-use it twice, you’re already money ahead.  Re-use it 10 times and it’ll be way less expensive than ordnance gelatin.  And, there’s no rush!  You can leave it stored at room temperature for a week, or a month, or a year, and it’ll still be there.  With ordnance gelatin, you have to use it within a few days or it’ll start rotting.

Testing ClearBallistics Gel

So, yes, I was very intrigued by this stuff.  I didn’t expect it to be exactly the same as ballistic gel (heck, one’s organic and one’s synthetic, after all) but — I mean, how good is it? Does it work? Can you actually use it and get usable, real-world results from it?

Let’s find out.  Head on over to the YouTube channel and watch the review.

 

 

Spoilers!

Watch the video first before reading this section.  Or, if you don’t want to watch the entire video review, I’ll tell you right now the basic take-away: yes, it works.  No, it’s not 100% exact.  With hollowpoints, I got about 94.4% the same penetration, and 94.5% the same expansion.  With buckshot, it was basically 100% the same penetration and 98.9% the same pellet deformation.  May not be perfect, but it beats the h-e-double-hockey-sticks out of shooting a pack of wet newspaper or a jug of water!  I was really impressed with just how usable this stuff is, and how close it mimics real ordnance gelatin.  It was basically 94.4% the same penetration, plus or minus about 5%, so definitely close.  I’ll be doing more specific tests to narrow down the statistical deviations and get a specific comparison, but for now, I would say that I would definitely trust ClearBallistics gel over homemade Knox gelatin, or wet-pack, or clay or wax or estimating penetration in water by saying “well, a bullet in water will travel about 1.6 to 2.5x as far as it would in gel”.  Those results are all unscientific and ballpark, whereas the ClearBallistics gel delivers results that are quite comparable to real ballistics gel, but without any of the associated hassles or inconveniences.  It ain’t perfect, but in my opinion it’s far and away the best substitute for ordnance gelatin.  If you can’t (or don’t want to) use the organic stuff, ClearBallistics gel is a great alternative.
