The standard loading for 30 carbine was, IIRC, around 40,000 CUP 'cause all this round was supposed to do was outperform the ballistic performance (and shootability) of 45 ACP (and the 1911); in the hands of cooks, truck drivers and other non first-line combat personnel.
The brass itself looks well -designed - with a strong web area - in spite of being a fairly-randomly-selected design - based on a rimless 32 WSL, neck-down to 30 cal.
Does anyone know what kind of performance could be achieved IF 30 carbine was loaded to more modern rifle pressures - like 52000 cup - using optimal, modern powders (like lil' gun?) - and fired out of a bolt gun - rather than the under-designed M1 carbine?
Could this brass have delivered 300 black-out type performance IF a better/ stronger M1 carbine had been made (for example, an imagined M1 carbine as strongly-designed as the SKS or Mini 14)?
Yes I know that such a round would NOT be safe in an standard M1 carbine. That is NOT the question.
