Ok. I'm not a big target guy. I'm a hunter. I don't care about a rifle being -200 MOA at 1500 yards if I'm only using it to hunt deer at 150 yrds. That being said even I can admit that the 17 hmr is more than just a novelty. For the small game hunter who wants something that can be good all around its a great cartridge. I've shot it next to my 22 mag many times and have found to be comparible. If you want something that can really perform that's the way I would go. If nothing else the ammo is going to be readily available due to the popularity of the round.
Now, all that being said, it is not a good gun for anything over foxes in size. I've shot around 30 coyotes with mine and have lost many of them. If coyotes is what your wanting to shoot get something bigger. As far as seeing it in used gun racks everywhere. I've not seen it.
