Air rifles are in a class of their own. You can get a decent powder burner for a few hundred bucks that will shoot straight. To do that with a spring air rifle you may have to go to the five hundred dollar mark or more.
That is not an absolute but a base rule of thumb.
I happen to love them and did not feel a bit bad spending $700 on my Air Arms TX200. I had to spend an extra $100 to get a left hand stock but that's the way it goes.
I often challenge friends with 22's to a 50 yard shoot out and mostly come out the winner.
Air rifles teach you consistent hold and trigger control and make you a better overall shooter.
They are cheap to shoot and can often be used in the back yard when other rifles can't.
If you choose to go PCP, the accuracy usually increases at the expense of convenience of use. Pumps or tanks are needed to fill them and worst of all, those who shoot springers call them "puffers."
