With a scant bit of fleeting time around the Holidays, I was re-reading references on the Belgian Proof Law & >>B. Blindée<< and its sister stamp >>B. Plomb<< were used since July 8th, 1910 but truly wasn't officially adopted / recognized until the 1924 Proof Laws.
Now scattergun pressure or tubes for shot, there exists quite a bit of info on proof pressure but for solid projectiles, info in lacking. The Board of Administration set the tone for breechloaders of Military Calibre and the Direktor of the Poof House established or cobbled together a Table for ball & powder. I would think that early on the Belgians followed the Brit's Table but soon they followed the German's pressures as the Germans were their main clients. I will search & try to find said tables.
