To contain the gases and prevent them from escaping between the fragments. Unlike HE, powders are too slow so it needs more distance/time to expand which means that most of the gases and energy will be lost.
pineapple casings are shit at fragmenting, sometimes it got decent but not really uniform frag and other times it just split the grenade casing without producing fragments
it was kept because the outside pattern was really good for gripping with the hand - but modern frag is pre-scored on the inside
I think grenades like the metal body so the pressure get high enough and the hardness of the metal causes a very quick and violent explosion.
A rubber body will make the pressure let out and not be effective.
>A rubber body will make the pressure let out and not be effective.
Not different from a gun. The idea is maximize fragment velocity instead of the blast's power.
The point of the encasing is to help build up pressure before the grenade actually expands so the shockwave is more of a spike rather than a gradual wave up and down, increasing the overpressure kill radius. It's why flashbangs are mostly less than lethal, because the explosive has a way to get out. Your grenade would work but it would be less effective.
A proper grenade is like how a mini pressure cooker bomb that turns Low Explosives into the equivalent of High explosives by giving the explosives time to fully combust before expanding, but in a grenades case it's with high explosives turned into ultra explosives instead.
Yeah, but the pressure wave is what propels your shrapnel anon.
It would work don't get me wrong, but a higher pressure wave would do the job at propelling the shrapnel better.
> at propelling the shrapnel better.
High pressure shouldn't be necessary if the gases aren't lost between the gaps. Propellants don't need high pressure to achieve 1000 m/s if there're no leaks.
What's with all the grenade threads recently
They're all made by grenadetard
happening soon
Antifa is prepping for election violence.
Why the rubber?
Our future chuddy terrorist probably thinks that the rubber might push away the shrapnel better or some shit.

Maybe, but you'd probably want to make it spherical the most reliably achieve the desired effect.
Seems like a great idea you should test it out by shoving it up your ass please post the results
Just make a pipe bomb, with a frag sleeve.
The rubber will do frick all, but an actual metal pipe will increase the blast.

So...a Pineapple casing?

except for the whole "no barrel" thing
It's a spherical non-barrel, the rubber works a sabot.
ok moron
Not going to do damage.
It's basically going to be at best a stinger grenade.

>overpressure
It's not about the blast but the fragments.

You would need a better explosive for the same result is the issue, it's not that it can't be done.
I've heard wooden fragments dipped in shit are devilish.
gunpowder burns too slow. the rubber will fail somewhere quickly and the burn off would just vent through wherever the seal is broken.
