I am looking for an identification on a 40mm projectile. I believe it is a newer type of projectile for shoulder fired grenade launchers such as the M203 and M79.
The projectile is not available for examination, but from photos and description I have the following data.
It is a 40mm and appears to be green plastic, with a flat point with a slight taper on the outside and a hollow that starts with a broad taper before becoming parellel sided. Parellel section about 13 mm diameter.
It has the following markings.
40 mm x 45
??? : 18 PIA
