I was at the range yesterday and I overheard my friend talking about World War II ammunition. It turns out that there was a fellow next to him shooting off a lot of old ammunition. I asked him what the headstamp was and said he did not know.
I picked up a case off the ground and it was steel cased ECS 43 . (1943)
ECS 43 indicates Evansville Chyrsler Sunbeam plant in Indiana. I told him that I was sort of a collector and asked if I could have couple of rounds.
He gave me a whole unopened box.
I snagged an extra round for dissection so I still got the whole box intact.
In actuality, this ammunition is not a rare item. EC arsenal produced something like 12 million rounds per day. A couple years ago I was tasked with stuffing magazines for a public sports fair and someone donated a pile of this old ammo for people to blow off. It is corrosive.
Here is the analysis of the ECS 43 round.

Caliber= 45 ACP
Headstamp= ECS 43
OAL= 1.265
Mouth dia=0.470”
Bullet type=conventional full metal jacket with sealer
Bullet wt=227.3 gr
Bullet dia=0.450
Powder wt=5.4 grains fine grey ragged flakes
Case=steel (galvanized I believe)
Lot# EC S-S25005

So what do you think the powder looks more like? One project could be trying to replicate the round in terms of today's bullet, primer, powder, velocity, and accuracy.

==========
powder could be anything 75 years ago

I went and shot some today and surprisingly, they all went bang.
The av speed was 858 fps with a sd of 24 from my 5.5" match bbl.
That means out of a stock 5 inch 1911 it would still make mil spec.....amazing
Even more amazing is that it was pretty accurate too. See the pic of the 5 shot group.

Very nice!  Old military ammo never fails to impress..  Even old 30-06 ball is damn accurate stuff.  Back then they really put their heart and soul into manufacture.  Life or death depended on it.

I dunno about 30.06.
I got a stash of Korean war vintage ball and when they did go bang, they went all over the place.

Regarding the war effort .....
Yes the human effort was remarkable.
If you Google some pictures of the factory back then, it was all women workers.
The men were in the military.
