I was checking on an undated Pakistan Ordnance Factroies catalog (assumed early 1990s) and have found an image of medium calibers which was the introduction to the medium caliber section. In the following pages some datsasheets with basic data are shown.
The puzzling thing is that the photo in the beginning is showing two 20x82 MG151/20 TP loads (top centre with blue projectiles). But they are not listed/described in the following pages of the catalog.
And as I was into medium calibers for more than 30 years this is now the first time I noticed POF being related to this caliber.
Anybody out there who has better/more info or even good photos of cartridges and headstamps?
