Excellent photos, Mr Heesackers - I wish I had one of those rounds in my collection!
Could I ask you for a couple of favours please?
First, I would like to know the precise dimensions of the case: especially the length (minus projectile), rim diameter, and diameter of the case above the rim. I would also be interested to know more about the performance of that round, in terms of projectile weight and muzzle velocity.
Secondly, would you mind emailing me high-resolution (300 dpi) versions of those photos? I am editor of the Bulletin of ECRA (Euuropean Cartridge Research Association) - which you may know of as it is very strong in the Netherlands - and would like to feature it, as it is very uncommon.
I have been trying for a long time to obtain clear information about which AAC cartridges went with which weapons, as they produced many different versions.
