I think the army corrosion issue was real but as I said they didn't care- the soldier would be killed or the war over by the time it became a problem. If I recall I think they also used a larger than normal flash hole in the nipple. This may have been to insure more blast from the cap ruptured the case and exploded the powder.
I think the testing was pretty fair- I think. I might be confusing the manufacturer but I think it was Johnson and Dow had some case-less cartridges. The powder was a solid and varnished. The army would soak the stuff underwater for 4 hours and see if the rounds still worked and sometimes they did and sometimes they didn't so it was an on again- off again thing. It would be neat to play around with the idea- no case no worry about unburnt paper or fouling in the chamber.
