I prefer to use the British term, "case shot," rather than canister as it gets around the problems of spelling the latter word -- two Ns, or one N.
In any case, David McConnell's book, BRITISH SMOOTH-BORE ARTILLERY: A TECHNOLOGICAL STUDY (Ottawa, 1988) contains a lengthy documented section on the evolution of British case shot from 1755 to 1860 on pp. 319-323.
He also includes appendices, pp. 502-505, which give the dimensions of case shot, 1766-80; 1780, 1828 and 1863. These are based on both published sources and mss in the RA Institute at Woolwich.
I do not agree with everything McConnell has to say in his book but, thanks to the Canadian taxpayer, which funded his research, he spent long periods in the library at the RA Institute in the early 1980s gaining access to primary source material which is now all but impossible to access.
