The carbines are good

Get the 10mm

10mm hipoint carbine lmao

Is there a cartridge in common use with comparable performance to .30 Carbine out there?

Yeah it's called 556

.30 carb is bad

Elaborate.

Exactly, like 556

Bad b8

If you're not putting 556 through a 20" barrel you're wrong and you should feel bad.

.300 is just 45acp but useful

And probably commit not breath

Only M16A1 should be 20"

Also, 1095STS 10mm carbine only weighs 7lbs, not bad

1095TS

What's the comparison between 10mm and .30 carbine assuming the same barrel length?

I mean if you want an even better round go .357 SIG

It's like 10mm Auto but better sectional density.

And slightly better BC

Also, comparing .30 carb and 10mm is apples to oranges.

It's a 7.62x32 against a 10x25, two different rounds for two different guns use din two different roles.

ewww .357 sig

It’s fast as fuck 9mm

It’s good

@FireRising I found test data for 10mm Auto out of different barrels up to 18"

At 18" the best performance was the 135gr @ 1440fps/~980ft-lbs

9x25 Dillon > .357 Sig

In real people units that's 1.38kJ and 439m/s for 10x25 as compared to 606m/s and 1.31kJ for .30 carb

Which is fucking surprising tbh

7mm more cartridge and holy balls the 10mm Auto would be a monstrous SMG/Carbine round

You'd be looking at like 700m/s and nearly 2kJ a round

at that point, why not just use an intermediate cartridge

7.5FK BRNO is pretty nasty for a pistol cartridge

nearly an intermediate rifle cartridge

Adding 7mm to 10x25 to make it 10x32 would give you another 2.56^3 cm to play with

Err, 2.56 cm^3

Imagine all the extra propellant

11.78 cm^3 total

longboi

10x32 would be a PDW cartridge at that point
