I would leave the hmr get a good serviceable .22 rf and the .222 the rimmy will do all you want on the bunnies ect and the .222 mustard on foxes ect and crows out to 300 yds , just so you know the hmr produces about 230ftlbs and the.222 around a 1000ftlbs,and is a very accurate round indeed, you do not need to spend 250 quid on a moderator for the .222 you should get a good used one for around a 100 quid,reloading will always produce a better round than factory if done properly, that said some good factory ammo like hornady ect will be accurate enough to do anything you need, cost should not m
