JSB Hades

I'm not a scriber of 177 for feather 22 for fur.
Low fpe and weight seems better for feather, in my observations. The sig 177 just passes through, the tx in 22 was pretty effective. High pass thru but less than sig.

Kruza, What caliber are you using for your bird control with the hades pellets?

Just did some calculations and u would need to push a 15.89gr pellet at 1310fps to generate 60fps!!!
Wow.
If u got a gun that can do that, it’s defiantly time to switch to slugs! Heavy ones!

Try hard air magazine too.
Do do something called the ham test for various pellets.
They are pretty comprehensive and also go into how dirty the pellets are,most common weight/head size, penitration, expasion etc.
Here is the hades review

Hi Kruza,
Not sure what the fpe at target is, but all shots were around 30m.
If those hades pellets are dropping from 13.6fpe to ….?not enough?.. in only 30m then there is something wrong!
Most head shots were pass throughs, so didn’t get to recover the pellet, but even with out looking at the pellet I can tell from the exit wound there was little to no expansion. I.e. has enough energy to exit but dosent expand much 🤔
The one pellet I did recover from a head shot was under the far side skin (nearly exited) and had expanded from 5.5mm to 6mm.

The high powered 31fpe shot on the possum was at about 15m. That should have still been carrying heaps of energy. It penetrated through the eye, exited the skull, traveled down through the neck and stopped just in front of the shoulder blades. Clearly had lots of power, good penetration, but only expanded to 6.5mm, not much at all.
This raises the question of “how much energy is needed to expand a Hades?”.

With regards to slugs, yes their terminal performance can be amazing, but I think they are usually made from softer lead, and have very deep “hollow point” cavity’s which helps their expansion. The also seem to like going fast, very fast, like 950fps and upwards! Unfortunately many PCP’s can’t push a heavy projectile at those speeds unless they are very “tunable”. They also need a faster barrel twist rate to stabilize them, so I’m told.
Their required speed and resulting energy with the added noise from the high powered gun probably makes them less suited to working in between horses.

I think the answer is a really soft pellet, with a deep hollow point that will expand rapidly at low velocity’s… hummm 🤔
