I am looking into getting a .22 rifle, probably bolt-action because the idea of a semi-auto .22 sounds absurd (though fun). I will never use a lever action again, they pinch! And anything larger than a .22-- the recoil sends the scope shooting into my eye. So yes, coordination (and generally being a girl) makes a .22 an easy choice. I am a decent shot at close range, but take me beyond 25 yards and I'm useless, unless there's a shotgun involved. Shotguns are the Windows of the firearms world-- just point and click. I've also found that I can't control a handgun, even if it's small caliber. I just don't have the motor control for it. I emptied a magazine in the direction of a target at about 5 yards with a .45 Glock (OK, that was not a small handgun) and didn't even hit the paper, let alone the actual target.
I really know nothing about firearms, though I enjoy shooting, but if you are unsure of your ability to handle one, I would suggest going with a .22 (there's no recoil and they are relatively easy to control) and with taking a safety course. Actually, maybe even taking the safety course before you make a purchase.
But yeah, I enjoy plinking.
