When young I used a Lithgow single shot bolt action to shoot .22 RF shot cartridges at birds eating fruit in our fruit tree orchards. Maybe twelve feet was a good killing range. I killed a lot of birds. Later graduated to rimfire ammunition with bullets. And the .410 with shot shells.

I also used the .22 RF shotshells against pigeons roosting in the hay shed. Furtherer than twelve feet maybe twenty feet plus. It killed them very well. The .22 RF shot also doesn't penetrate the corrugated iron shed roof. So no bullet holes.

I've also used these .22 RF shot shells to shoot venomous snakes I've found inside the sheds. In the body disables them. In the head kills them. If a snake is behind a cabinet or storage shelves one might see only part of the snake. So a first shot to disable it. Snakes are protected but can be killed if endangering human or pet or stock. Nowadays wankers get very upset if a snake is killed, they "love snakes". Think a snake catcher should be called instead ... I've got no shortage of these deadly aweful things.

Rimfire shotshells kill rats in the sheds as well very easily.

Rimfire shotshells will kill larger than rat pests in the sheds as well if shot in the head, but I won't describe these roof nuisances.

I think our shot size might be 9s (?).

I've never patterned how they pattern in a Lithgow single shot rifle.
