Both. A couple of CZ's using the same mags and same FFP optics.
.17HMR for when the weather is calm and the ranges are >120m on rabbits and hares.
.22WMR for when the wind is blowing harder and the majority of range is <120m, and where you could run into something a bit bigger, including a deer (head shot only), and for night shooting rabbits.
In my experience, the .17HMR is inherently more accurate than the .22WMR
