I'd pass on the 22 Hornet. If you want a Ruger, take John's advise and go with the 17 Hornet. I have a CZ in 17H. The 17H pretty much makes the 22H obsolete.
I do have a #1 in 22 K Hornet, but that's another story.
Not real hard to make a K-Hornet out of a Hornet. I did it, first try.
Here's a link to my CZ 527 project. Lots of good info on loads, JB wrote some really good stuff (no surprise).
Also a good bit of B.S.; my threads tend to wander off in that direction...
This CZ has a .224" bore with 16 twist.
