Calling someone the french is a low blow

That was pre-modification Squid

lol

HK designed an entirely new explosive just for 4.73

I mean that in a "we have 8 different calibers and rifles because we kept everything from a century ago"

french

It set hard, had a stupidly high heat tolerance, and was difficult to break.

Oh no, I get it, I still find it funny

caseless is being developed right now with polymer

Like post-redesign the 4.73 round was actually harder to set off than conventional brass

less worry about the HK style of caseless

Polymer semi-caseless has been done for almost 40 years now

"done"

MAC, do you know how NATO 120mm tank shells work?

yes, it's nitrocellulose with a baseplate

It's a semi-caseless polymer round with a metal abseplate.

I'm saying for small arms

It's the same difference, you're just caught up in scale.

different problems

I don't think the tech works that way

The only problem with nitro is IIRC water resistance

It melts like butter if you get it too wet

Which can be solved by using a thin layer of thermoset that's below the adiabatic flame temp of the propellant

I'm surprised the military had enough braincells to look at telescoped rounds

logistically speaking it makes sense

weight reduction

but then they smoked crack and went with 6.8mm caseless

because reasons

@Magos Squid "The Life Raft" sorry to derail your whole conversation....

So what I'm reading is they went with a medical polymer that was fuckawesome, and easily coul dhave been *cheaper* than brass

6.8 Remington is used by the Czech in a variation of their 805A1 combat rifle

Easier to produce too, like, 11 less steps to make a bullet easier

It's not 6.8 caseless but it still a weird round

the jordanians use it as well
