Major Walter Schmidt: 
I think is very similar to something…
Hallo, I need to remember that the “thing” above have already its own topic so…
Since the subsonic rounds are (perhaps in error, tho I think more knowledgeable heads will know the answer to this) widely supposed/attributed to have been manufactured for the Vampyr application among others, I would have little doubt they’d be lethal within the given range, notwithstanding that said range is less than that of a standard round.

The aplication of the german short range ammunition in the battlefield was really limited, most of the scharfschützen prefered to use the normal SS and to shoot from long distance instead to use the nahpatrone at 100 or 150 meters away of its target.
I guess It was mostly used for internal security affairs and antipartisan duties.
The nahpatrone for the 7,92x33 would be problematic , probably it didnt work the action properly making the gun in manually operated instead semi or full auto.
