Not impressed with .22 JSB Hades

You have to realize that the expansion you're seeing is a result of striking a hard surface. Bone ! High power center fire projectiles will do that just passing through the ribcage and then into high liquid content internal organs. It's all about hydraulics. Most airguns just don't obtain enough velocity to achieve those kind of hydraulic results.

I've found a good expanding projectile can make a huge difference with "hydraulics."

Polymags, for example, open a cavity and leave a large wound/impact channel that you don't see with diablo's.

I've seen a hollowpoint turn tissue to mush and create an exit wound much larger than the entrance wound.

In my experience, it provides extra insurance which can make the difference between a runaway and dinner.

At that all depends on what kind of airgun we're talking about when it comes to expansion. Firing these types of pellets in a high power PCP will achieve good results. Now fire them in a 650 fps breakbarrel and the difference we'll be astronomical.
 
I can ATTEST to the .22 HADES! This was less than an hour ago and the VERY FIRST TIME with the LESHIY! One shot, look at the hole!

What velocity? I had them screaming out of the barrel and still no joy. I wonder if there is a lot of variance in production with Hades. Read recently of people having serious accuracy problems with a .25 caliber batch.

I just picked up some tins of Predators for the .22 and they shoot laser accurate. The Hades will end up as plinking fodder.
 
If you are shooting them at very high velocity you are getting pass thru’s you are NOT dumping all the energy IN the Animal

That is an oft-repeated misconception. The goal is not to dump _all_ the energy. The goal is to dump the _maximum amount_ of energy.



Consider two identical pellets with identical shot placements, but delivered at different velocities. Pellet #1, the slower one, plows through and stops under the hide on the opposite side, dissipating all its energy.



Pellet #2 arrives at a higher velocity and passes through. However the elevated velocity causes greater deformation which in turn allows it to interact with more tissue on its way through. And in so doing, it will have dissipated more energy than the slower projectile. Additionally, the elevated cavitation behind the projectile expands the region of hemorrhaging. Altogether there is a greater amount of tissue damage and trauma, making it more effective. 
 
If you are shooting them at very high velocity you are getting pass thru’s you are NOT dumping all the energy IN the Animal, I also shoot predators, HADES shot at lower velocity do way more damage than predators. Edgun Leshiy has a YouTube video explaining this.

That’s where I learned this.

That doesn't make sense. Higher velocity always correlates to higher expansion and higher expansion leads to more damage. Given two pellets of equal weight, you will have fewer passthroughs with the one with greater expansion.

If one pellet doesn't pass through while another does at a similar distance it is almost always the case the one that doesn't pass through had done more damage.

Hades pass through more than Predators because they expand less and do less damage.

For a specific example I hit a squirrel in the brain cavity with both a Hades and a Predator. The Predator's exit hole was large enough to fit my finger in and the damage was impressive. The Hades exit was indicernable from the entrance. 
 
I did an experiment with some NSA slugs in my bulldog and jsb ultrashocks in my marauder. I took a razor blade and very gently and precisely made incisions straight down into the hollowpoint of each in a perfect + pattern. Back in the day we used to bang a phillips head screwdriver into the tip of .22LR rounds to make a "kinda-hollopoint". Regular ballistic gelatin and the expansion was insane. The NSA slugs opened up like a .45ACP fired into water, the JSB's similarly but had 4 distinct petals. Unfortunately the JSB's were never accurate and the cutting didn't help any which is why I was ok messing with them. The NSA's had no POI change. Afterwards I called Corbin regarding making a mold like the NSA's (he supplies NSA with their molds) but instead of the normal ejector pin producing just a hollowpoint to have one machined with 4 razor thin sections to create 4 petals on impact. He told me that although it could be possible there were two problems. Normal tool steel might not be strong enough to withstand the pressures during swaging and/or using something like carbide could possibly work but the machining would be cost prohibitive. I was supposed to have my son draw up some stuff on his CAD program to send to him but haven't gotten around to it. I've taken a couple of 'coons with the cut NSA slugs but never dug them out. I'll tell you what though they dropped like a sack of corn.
 
Well, after the Chinese barrel lottery and the Chinese regulator poker — are we now having a Czech hollow point-expansion roulette when we're trying to shoot the Hades...? 🤔



Somehow, despite high praise of its expansion, there is also disillusionment with the lucky streak from Hades — it seems not to pay off and expand, despite the high bets and fps we invested in it.



I mean, if your gun shoots the Hades more precise than the regular domed JSB 16, by all means use it! 😊

But Hades has a much lower BC of 0.023 than the JSB Dm 16 (0.031). So, more wind drift, more loopy trajectory, less energy on target.... 🤔



Just wondering out loud if I should to go through the hassle of getting a bunch of Hades from the US to Peru.... (down here they are N/A).



🔶 Maybe some other shooters could share their experiences. 😊

I'm especially interested in heart/lung shots on pigeons, with impact velocities between 450 and 900fps (.22cal).

I've only shot one critter with mine. A ground squirrel at about 45 yards. .22 JSB Hades going 760fps @ the muzzle. Taipan Veteran Shorty.

The ground squirrels are typically very hard to kill, usually requiring head shots. I can think of only a few instances where a heart/lung shot kept them from making it back to a nearby hole before expiring. 

So, the above gs was quartering away and I made a split second decision to just try a heart/lung to see if there would be any difference. Impact point was spot on. He looked like the switch just got turned off. Found him right where gravity landed him, no twitching, movement, etc. Lots of blood, no exit, but bulging mass and what looked to be broken ribs pushing from the inside towards the bulge on what would have been the exit side. 

N of 1 isn't statistically useful usually, but warranted and elicited a serious literal and metaphorical raised eyebrow. 

Accuracy is quite good too. 10 into less than an inch at 55 yards pretty regularly. Dang good for a novelty hunting pellet. 
 
Took this guy this morning at 75 yards with the .22 Hades out of my Wildcat. I have shot plenty of house sparrows and starlings over the years with JSB 15’s and 18’s and I can say unequivocally that the Hades has more effect on the birds than standard diabolos. At 35 yards it literally tears sparrows apart and leaves gaping holes in starlings. I have also noticed a more distinct “pop” when they’re hit with the Hades, even at the extended ranges.

First tin of 16gr .22s shot like the 18s very accurate but bought an other tin and results no where near the first tin?

I've heard of people having accuracy issues with batches of Hades. One guy mic'd the head diameter and found the new inaccurate batch was smaller. I suspect the head diameter gets expanded to size when the pattern is applied and if they don't get just the right amount of forming the head size comes out small.

I find the NSA hollowpoints open up great as they are. However, if you want to add splits you need to do it in stages instead of cutting the splits. You need to form pedals in the first operation, then fold those pedals inward in the next operation. I'm sure Corbin could help you with such a die. It takes a 2nd operation is all. There are slugs made like this and when sold they cost a little more because of the extra forming operation required.
