.22 Calibre or .17?

[M4verick]

I am looking into getting a small calibre firearm for gopher shooting and target practice. I have plenty of experience with .22 rifles and I have never shot a .17 calibre. I know .17 calibres are more expensive in the long run due to ammo but I can never confirm this. Can anyone provide me with input? If you recommend a gun, what model? Keep in mind I need something affordable...bolt action, with a clip. I dont want to spend over $350 on the gun (brand new). Any recommendations would be great!

Thanks
