25pdr cartridge dimensions.

Recommended Posts

Does anyone have a drawing showing the basic dimensions of the 25pdr cartridge ?

 

I'd like to turn out of brass some for this 1.6th scale 25pdr kit but I've not managed to find a complete drawing yet.

 

The dimensions I've found so far are that it is 292mm long, with a 105mm rim.

 

I would be grateful to know whether it is tapered, and if so by how much, and the approximate thickness of the wall.

It isn't tapered and it measures 3.45in / 87.63mm at the neck. (The very earliest cases made in 1937/38 are marked 3.45" rather than 25PR) Case thickness is about 1mm.

Many thanks for the information, that's just what I need :-)

 

I've made a few test runs and managed to down get to a 0.25mm thick wall, which is thin enough to look the part.
