Venturino comments that the commercial loads of 45-90 Winchester never contained less than 100 grains of powder, accomplished by shallow seating of the 550-grain bullet, whereas the same 2.4" case with a fully seated bullet only has room for 80 grains of powder. He thinks this is fine, as it was designed and sold as a target shooting cartridge and is over-powered for that purpose until you get past 500 yards.

That is backwards. The .45-90 Winchester was loaded .45-90-300 for the 1886 repeater. There is such a thing as a .45-80 but it is the same case with a heavier bullet and less powder space to feed through the lever action.
Sharps usually referred to their cartridges by case length because they offered different loads. The 2.1” was typically a .45-75 from Sharps vs .45-70 Government or Winchester.
