Tom:
Here are the 12-bore Paradox diagrams shot at the 1886 public trials at Hollands' shooting ground at Kensal Green.
Fifty yard diagram, size not specified but all ten shots went into the 3 1/2 inch bull.
Hundred yard diagram, measuring 5 3/4 x 3 3/4 inch. Number 4 was obviously a 'flyer', as a second group was shot to accomodate a late-comer to the trial, whereby all ten shots went into 3 1/2 x 4 3/16 inches.
I would conclude from this that 2 inches at 50 yds and 4 inches at 100 yards is not only perfectly satisfactory, but rather excellent, especially if it can be sustained for ten shots!
