You hit it exactly, what is "normal wadding"?, when I started with a muzzleloader shotgun, I got a different "normal" load from everyone I asked.
To this day I don't know what would be considered "normal wadding", I know my first few range trips almost made me give up on the gun.
I think when people say normal 'shotgun' wadding, the mean just that - normal wadding - the way shotgun "shells" were NORMALLY loaded since that era of enlightenment(breech loaders), but prior to plastic wads.
Normally consisting of:
1/8" to 1/4" over powder hard card wad -
cushion wad9s0 of various heights from 3/8" and thicker - of compressed horse hair if you are Russian or today mostly donaconna
thin overshot card - again, normal. The normal crimp was a rolled crimp. Normal for Frnech shotshells was a clear overshot card, so you could see the shot size.
All of these are normal shotshell wadding. Today, there are a miriad of differently shaped and sized plastic wads, so they are also now quite 'normal'
The standard cards, fibers, etc are what is usually considered normal.
For the filler, cushion wad, there was a Swedish cup-wad which improved patters somewhat in cylinder bores, but more so in choked bores. Other loaders used 2 cushion wads, one with
a hole in the middle to hold extra shot, hidden but only known by the loader. These were used mostly for cheating at patterning contests in England as the hollowed out wad held 'extra shot' which struck close to the centre of the page, thus seemingly to increase the shot count. Some of these sort of ideas might help today for increasing shot in the killing pattern, which is why some experiment with post-it note pad papers and coin wrappers. Those might just be the trick for getting usable long range patterns, just like the Green wrapped Ely ctgs.
Out to 40 or 50 yards or so, they shot like a slug, meant for shooting deer and wolves, only letting the shot fly freely, after that. There were even ctgs. of shot for shooting out to 100yards in the larger bores.
There is no normal wadding for muzzleloaders. People NORMALLY use whatever they can invent or imagine, from toilet paper to old rages to wasp nest
