Though significantly lower powered than the .250 Savage, I wonder if it might be possible for the US army to run with 'modernized' .25 Remington cartridge based on existing experience and have the first intermediate cartridge/assault rifle combo. Even if just for their M1 Carbine.
Interestingly that cartridge ended up producing a necked down .22 with performance and size very similar to the later 5.56 NATO...just in the 1930s-1940.

Testing in the early 1920s led the Ordnance Bureau to identify three rifle designs - the Bang rifle, the Thompson Autorifle, and the primer-protrusion actuated Garand Model 1919 rifle - as promising candidates. However, all three designs were burdened with the high pressure and heat generating characteristics of the .30-06 ammunition, which looked likely to result in a weapon too heavy and too subject to overheating to be worthwhile. Trials with a small number of "militarized" .25 Remingtonautoloading rifles, despite their unsuitability for combat, provided a body of practical experience with semiautomatic rifles and an appreciation for the idea less powerful ammunition might be a critical part of the successful development of such weapons.

Harvey Donaldson also used the .25 Remington case in early experiments that would eventually lead to the creation of the .219 Donaldson Wasp. Donaldson later switched his experimentation to Winchester .219 Zipper brass after the launch of that cartridge in 1937.
