I have recently got a job of controlling rabbit numbers on sportsfields at a school. The lye of the land means ricochets are a no no and as we all know the .22 lr loves to bounce.
So I'm after an alternative.
The options are the .17 hmr. But discounted this as noise is an issue as being a boarding school making your presence known to the students isn't great.
Are lowered powered.22 rimfire cartridges a viable option. I've no experience of these.
I used my .177 air rifle with night vision scope to good effect but a little more range would be an advantage so is an fac air rifle a good compromise.
I await your wisdom.
