drhall762: The water-table should tell you a lot about the guns original proof - you may well know this.
Also found more paradox articles in DGJ, Winter 2010 & Spring 2015 by Sherman & Ross.
They both agree that a bullet 0.001-0.003" undersized is the key.
Seems H&H introduced the Paradox in 1886 (from Fosbery 1885 patent) and by 1905 Holland was offering 'magnum 12-bore & Long Range Paradox" this seem to be the time H&H went to Cordite.
Interesting a H&H Royal Grade Ejector 12-bore Paradox made in 1895 loading instructions state "3 drams no.6 powder".
You will enjoy all the reading...
