50x228 Bushmaster XM913 ammunition

I just came across these images in the web and tried to find more info on the ammunition.
Does anybody have more data and images?

Not actually completely sure if the larger ones are 50mm or 40mm.

Correct, the two in the centre are the 50mm.

Spaceinvader, I think you will make @APFSDS wet his pants :wink:

but wait, are we looking for 50x228 or 50x319?

Must be around 228mm as 319mm would be too long here.
The original Rheinmetall was 50x330.

Ok, it appears that the bushmaster III can be adapted to either the x228 or the supershot x319

Starting from the Rheinmetall RH 503 in the late 1980s which was 35x228 and 50x330, just the barrels had to be exchanged.
Back then we were about to adopt the gun with the new IFV Marder 2 but due to the fall of the USSR all got cancelled.
Means back then it would have been the heaviest armed IFV around. Now 30 years later it is sold as the new super gun. And instead we just have adopted the puny 30x173. What a shame!

I still wonder what the connection between Rheinmetall and Bushmaster is.

Thanks for the confirmation, wasn’t sure of the case length.

I am not sure about the two case lengths the US are using.
It would be good if somebody could confirm.

This picture shows the x228

Is the 50x228 confirmed somewhere?
Has somebody a case he measured?

It is marked 228 on the base in spaceinvader’s picture.

Just for the record, I was looking up the RH 503 and found the 50x228 case to have beeen part of one of the RH 503 design stages which back then settled on 50x330.
Means the 50x228 case we see here is not new at all.
