WI: European Intermediate Cartridge in the 50s

Inspired by Maximinus Thrax IIs thread, I got to wondering , WI Churchill, instead of stopping the development of the .280 British cartridge, had instead seen its value, and tried to sell the idea (if not the cartridge itself) to the French and/or other European powers? Could he have been successful? And what might have been the effect of the European powers having an assault rifle in the 50s?

No. The Euros were broke AF and the US was the paymaster, so would get what they want. The French were never not going to keep the 7.5x54, because it was already in production and they were not going to pay to adopt a US cartridge with the same performance. The only potential option for an intermediate was everyone just saying 'screw it' and adopting the 7.92 Kurz considering it was already ready to go, there was all the barrel and case making equipment that the Euros could need because Germany wasn't allowed to keep them, and even the FN FAL was originally designed in 7.92 Kurz.

If only they had read the Kent report...
 
Well 7.92 x 33mm Kurz works for the purposes of this WI, just as long as at least a few countries adopt the thing into service for an assault rifle.

I guess have FN keep the FAL in 7.92 and have the Brits stick to their guns on the issue since they already had 7.92 case and barrel equipment from WW2 plus German captures. The Brits had already considered adopting 7.92 late in WW2 anyway. So maybe Churchill doesn't come back and the Brits just opt for the cheapest option, the 7.92 Kurz and FAL.

That would mean abandoning their .280 MMG plan, but they had Brens already, just keep using them and do a better job on designing a belt mechanism. Actually that would probably end up being much cheaper than converting to 7.62 NATO. Ironically West Germany probably has to convert to 7.62 NATO, like it or not due to the US equipping and funding their military at it's refounding, while the Brits have 7.92 Mauser.

Germany has to convert to 7.62 x 51 NATO for their Battle Rifles and Machine Guns, but the 7.92 x 33 Kurz is a less powerful cartridge, so there's nothing blocking Germany from adopting it alongside the NATO one, unless the US has specifically banned them from having intermediate cartridges.

Finances would prevent them from adopting it, since they'd have to buy 7.92 barrel and bullet making equipment, plus maybe case making equipment, since it is a bit different than 7.62 NATO.
 
And maybe this time the American can come up with something with a bit more of an inherent punch than 5.56 x 45mm NATO.

What about a French 7.5 Kurz with GB and Belgium going together on it early?
Why would anyone? They'd have to pay for a new caliber production equipment anyway, so why not their ideal in that case?

It would save the French a lot so more likely to be agreed to if a joint project, GB was going to need new tooling anyway as the 303 is rimed so not suitable to use, the issue is that going to a 7.62 30-06 Kurtz (ie even more so than 7.62 NATO is) is more likely as US is more important supplier....

British already have tooling for making 7.92mm bore that was used for the Besa MG. They were also making 7.92mm x57 ammo.
OTOH - how about 7.62 Kurz is also a good idea.

Almost there, really.
Move the Brits away from Cordite strands to flake or extruded powder, you can shrink the case while keeping enough capacity for modern propellants
at the desired velocity
