Post-it notes can also be used as shot wrappers. Some have claimed good patterns at longer than 25 yards, which seems close to the limit of most cylinder bored guns.
There are lots of tricks can be used or experimented with. The Swedish Cup wad was noted by WW Greener in the 9th Edition of "The Gun and it's Development". The 1st Edition
was written by W. Greener, in 1858, seems to me.
One of the Ely ctgs. was noted in Firearms of the American West in a contest between a 48" barreled 12 bore fowling gun, and a SxS 14 bore English gun the American called a "little pistol".
The contest was at 75 yards, on a 4" x 7" piece of paper.
The 12 bore long gun made 4 pellet hits on the paper.
The "little pistol" made 28 hits. "Old Tom" remarked, "now don't that beat all". Love those books. The documented "anecdotal entries" are wonderful.
