Rabbits out to 150yds, lots of them without the hassle of reloading buy a HMR, I use one because I cannot simply be arsed to reload 50-100 rounds at a time, the HMR allows me to use NV and thermal at night with its flat trajectory and range is not a huge issue within reason with it..
Rabbits and fox out to 200yds buy a .22Hornet
Rabbits and Fox out to 300yds buy a .223
Rabbits, Fox, Deer further buy a .243 , better all-round than a .22-250 IMO and fully legal on all species.
