Just out of interest, how much firearm experience do you have? Are you a new shooter or do you have a bit of experience with larger calibres etc? The reason I ask is that although the HMR is great for newbies, I think there are better choices.
I started out with a HMR, still have it. If you want a grab it and go rifle then they're great. I've recently started shooting a .22 Hornet though as I can load it for the same cost and it's got a little bit more power. I shoot it just like I used to the HMR, but feel it's very useful to be able to take a Fox at HMR bunny range. The Hornet isn't harsh to shoot like the bigger .22 centrefires, but has a lot more potential than the HMR.
I may be going off on a subject you've already researched or are not interested in. But if you're still open to ideas then doa google search on the Hornet and have a read. I only mention it as I've found it to be so much better for my needs!
