You can enter 'wadding' in the search box and find more hits

Not easy to read. Looking at page 239 it would seem a thin field card vs. a thick field wad produced a slightly better pattern. All things being equal I would expect the longer shells with equal payload had "thicker" wadding. Could the longer shells with thicker wadding have reduced pattern effectiveness? However there is more information to take in here. what's your take?
