I knew that,Sure it makes sense, so that's why the Army wouldn't do it.
I'm thinking of something akin to the 7.92mmK, so it outperforms the .30M1C without being insanely powerful for less well-trained troopers. (Bullpup is probably out of the question...An early Assault Rifle still isn't a PDW. Tough to get rid of the 1911, even though any pistol is a terrible PDW
Say your round is pretty much a necked down Winchester .351 Self Loading ...also fills the role for support personell that the M1 Carbine filled.
Rimless version of .30-30 perhaps?I knew that,so let's leave rationality (or not) out of it.

And I had in mind it taking over the M1C role. I pictured officers not needing the M1911, too. (In this era, the tunnel rat isn't a factor, so given Vietnam happens as OTL, something else may need to be developed, tho, TBH, by that era, I imagined a bullpup caseless rifle being standard ish...
{Yeah, that's ASB against OTL

Extreme case would be the Mondragon rifle or similar entering limited production a decade sooner. This batch is credited (justified or not) with battle sucess thus sparking development of 'assault' rifles.
Actually, per ".30-'06 Short", a shortened .30-'06 (case 40mm v 63 of the '06).Rimless version of .30-30 perhaps?
