The problem I have with a hornet is that you basically are forced to reload it. With that being the case, you could just as easily down load a .223 to match performance of the hornet and then have all the advantages that come with the .223 case (a little easier to load, much more availability of cases, cheaper cases, etc). You also have the option to then load them to full potential if needed/desired. The reason I'd jump on a .22 hornet is if it comes is a more handy rifle than a similar priced .223.
All that said, the hornet does a lot of things right. The K-hornet removes a lot of the complaints of the standard hornet case design and makes it easier on reloaders. Some claim to never have a problem with the standard hornet case but others, even veteran reloaders, do have initial growing pains learning how to load that little case properly. The hornet plays a great role in that it pushes varmint type bullets pretty fast yet is much quieter for neighbors and is much more efficient in it's powder use. If you live with neighbors within a few hundred yards, especially the type that aren't gun friendly, it's a much better option for short range varmints than a full power .223 or up and extends range a bit from .22lr. Sure, it isn't the round I'd take to camp Perry to put on the 600 yard line but it does what it was intended to do very well and is a great option for people with sound restrictions.
