New to hunting?
A 22 bolt action.

EVERYONE needs to start with a bolt action or a single shot 22. You will need to learn safety first. Then you can go get a semi-automatic 22 next year.
The year after that, you are REALLY going to want to start in on the higher power rifles

First rifle NEEDS to be a bolt action 22 for hunting small game!
I have a 22/.410 over under that I use for training my children. I still use it myself now and then for a rabbit hunt.
