Intermediate cartridges

The armies of ww2 were glutted on outdated but relevant equipment, and the interwar period held back development.

the only thing that really developed during the interwar period for most major countries was planes and tanks

I mean seriously, imagine if they lengthened the case and gave it a spitzer bullet. We'd have .300 Memeout over 50 years earlier, albeit it would've been a larger and heavier round.

Or they could've had a longer case and a slightly smaller caliber spitzer bullet. That would've weighed less than 1940's memeout and extended the range and lethality by a pretty huge margin compared to the .30 Carbine we got.

Either way, a slightly more powerful round in a slightly heavier rifle, and the Garand would've been a rare sight by Okinawa.

Son, 1920-30s is still bolt-action Rifle Era.
Even cheaper SMG is not widely use by Military.
And Only USA can make so much bullet for auto-rife.
The Main Powers are still have millions of Bolt-Action Rifle, and they have no money to replace.

Experimentation on semi autos was extremely widespread and one of the key problems they were running into was making a sufficiently strong and reliable action for a fullsize cartridge in a package of practical size and weight.
The problem was less price, more just getting the damn things to work. Once tooling and shit is set up an automatic isn't that much more expensive than a bolt-action.

Intermediate rounds make it much easier to design an automatic weapon, even if an early intermediate rifle was more SKS than AK, and weighed more than it had to, it would've been a major step up.

You do know about operating pressures too right? They didn't want guns that operated at low pressures because you ended up wasting case capacity. The .276 Pederson is almost a perfect example of this. It has a very large case for how little power it has, but it ran like a dream in semi-autos. One of the reasons the US was willing to adopt 5.56mm was because it finally had the higher operating pressure that cartridges like 7.62x51mm and 8x57mm Mauser had been running at.

Winchester was in charge of the caliber creation. They basically said "Fuck it" and recycled an older proprietary cartridge

I think that even when WW2 started, military theorists still thought that the range of most of engagements would be longer than 300 meters. It looks like they intended on using the full potential of old line infantry rifles and only thought of changing when they were faced with absolute necessity. Even the Wehrmacht had very few sub-machine guns per company before the battle of Stalingrad.
When they figured there would be more close-quarter engagements than they previously thought, they still didn't see the need for a new type of rifle because that role was already fulfilled by sub-machine guns (and you don't need that more firepower when kevlar hasn't been invented yet).

At least that's what I think. Tell me if I'm wrong.

Aircraft carriers entirely upended hundreds of years of naval doctrine.

Aircraft developed during the interwar years in general entirely changed how the war played out.

This is the only reason the Garand didn't use an intermediate cartridge - the US still had warehouses full of .30-06.

And yet, they made the M1 Carbine

1. Intermediate cartridges weren't developed until there was someone who actually made a study of the typical ranges and rate of fire used on a MODERN (read: not WWI) battlefield.

2. That data wasn't available until the middle of WWII

3. America, Britain, Russia, and Germany literally developed intermediate cartridges and weapons as fast as they could.

4. What the fuck is Anon EVER talking about?

1. Experiments with intermediate cartridges were well underway in the 30's

2. There was plenty of data already

3. American retard doctrine stood in the way of intermediates

4. Eat shit tripfag

The carbine was designed to fill the slot between a 1911 and the M1, for guys who needed more than a 1911 but weren't necessarily a rifleman. Like mortar crews, artillery, radio operators, and of course airborne troops.

The Carbine was fine for its intended purpose. It was supposed to be a a personal defense weapon for tankers, artillery and rear echelon troops. Hundreds of thousands were made because there are always more support troops than front line personnel. Then a few front line troops got ahold of it and realized it was a great little rifle for close in engagements. Officially, the Garand remained the official front line combat rifle. It's also important to note that the M1 Garand was developed in the inter war period when budgets were tight while the M1 Carbine was developed after the war started and the war department was throwing money at weapons development and procurement. The M1 Carbine was first adopted in 1942, The M1 Garand was adopted in 1936. It still took all of WWII and the Korean war for the concept of the intermediate cartridge to be accepted, and even then, old hands fought it tooth and nail and attempted to sabotage the introduction of the M16.

Because miltary are drooling retards.
>muh cartridge power
They were against detached high capacity magazines because they would impede parade exercises with rifles. I kid you not.

What do you call .56-56 Spencer and .44 Henry if not intermediate cartridges?
