I will happily identify myself as a .22 Hornet fan boy.

However, I have ended up converting all my .22 Hornet barrels to .22 K-Hornet.
Lot's of benefits; much better case life when reloading, fireforming .22 Hornet in .22 K-Hornet barrels is not only quick and easy, but you lose no accuracy when shooting the Hornet in a K-Hornet barrel, and of course, you can up the ante for powder charge if you like.

For powder, Lil'Gun is my only and ever "go to" powder for handloading the .22 Hornet/K-Hornet.
A really fun cartridge out of a Contender pistol.
