12 Ga shotshell?


Hello everybody, I have had this fired case for years now but I have no idea for what it was used.

On the bottom is printed
20 TP-T ROCK G83 M73
Lot 01 MPA 81

It is a 12 Ga from Cooppal Wettern from Belgium.

Any help would be great.


Hi René, this is a 20 mm target practice tracer cartridge used with a subcaliber training device mounted in the Belgian Mecar 83 mm rocket launcher. It was loaded by PRB for Mecar using modified shotshell cases.


You are a wealth of information and a star on this Forum…thank you


Hi Fede, indeed you are a great supplier of information.

Many thanks.

PS is this fired case collectable for anybody??
