In a word, "yes", for action inside the 250 yard marker. Like you, I've got lesser and more intense calibers, but really enjoy the light report and measley powder consumption, and still be able to make good hits on PD's and squirrels at 250+ yards. The wind is the determining factor when using the Hornet, just like the 17HMR.
A couple of days ago when the wind got up and we took down our rat benches, I used my 22 K-Hornet for cruising around the ranch shooting out the window of the truck using window bags, and still got nice thumps much farther than my 17HMR's could have done considering the wind factor. The Hornet hits with much more authority on these critters too, just by virtue of bullet weight. (Scroll down to my post on the 22 K-Hornet to see what I mean.)
In improved form, the 22 K-Hornet can launch the new Barnes 30gr Varmint Grenade at almost 3,400 fps. To me, it shoots like my 222 Remington, but uses only 13.0grs of powder. Pretty efficient, and I can load any of my Hornets cheaper than I can shoot my 17HMR's by virtue of being able to reload all of them.
If you're on the fence and have never owned a Hornet of any kind, you're in for a real treat. I've got Hornets in regular flavor, 22 K-Hornet, and 17 Ackley Hornet. Think of it like this: "Hornet = FUN"
