Okay, I come from a long line of .22 Hornet owners, I have owned one myself, and have used it on targets and game. If I had unlimited funds, I would have one or two in the vault again.
That being said, I think that a lot of people would be better served if they would consider a .218 Bee or a .222 Remington instead of the .22 Hornet.
The brass thickness and case design of a .22 Hornet leave a lot to be desired when it comes to reloading. It's easy to ruin a case mouth, and the case taper (instead of the shoulder) lets the foil thin brass become even thinner fairly fast. A .218 Bee or .22 K Hornet helps alleviate this with its shoulder and losing the taper, but it still is awful thin brass for the K Hornet...
It used to be said that one could never hope to get sub MOA groups with a .22 Hornet, but I know that isn't true, at least these modern days. However, I can't imagine ten .22 Hornet rifles known for their accuracy going toe to toe with ten accurate .222 Remington rifles, and the results of who comes out on top ever being in question. Reloaders can turn their .222s into .22 Hornets by loading down, but a .22 Hornet can't be loaded up to match a .222 Remington.
However, we can all just say "Dang it! I like the .22 Hornet, and to heck with practicality and logic, I'll take it over any other .22 caliber for my crows and woodchucks, because I love that odd looking little cartridge and the good times we have had!" I know that is what I used to say, until I was swindled out of mine by my own brother...
