The .218 Bee always used .224" bullets.
Many (but not all) early Hornets (1930s, and 1940's) were made with .223" bore diameters. That was stopped in the late 40's/early 50's, when the Hornet went to .224 bore.
The .222" bullets were made for the 22 Jet, a very (VERY) short lived pistol cartridge from the 60's, made by necking down the 357 Mag pistol case - S&W Chambered an "N" frame revolver for it, that would not work. The cartridge was made to use .222" bullets so the interchangeable cylinders would allow 22 rimfire to be shot in the same gun - the firing pin had a switch to allow changing from centerfire to rimfire.
The Hornet never used .222" bullets.
Using .223" bullets in a .224" bore will work, but might not give best accuracy, but it will certainly be fine for critters.
