I haven't bought a gun in about 5 months so I decided it is time to buy a new one. I have decided on a CZ 527 American in either .17 remington or .204 ruger. I would like any input on the pros/cons of these two calibers. Ballistically, they are almost the same. My main concern is that the .204 is new and will there be ammo readily availalbe 5/10/15 years from now I don't have time to reload. Any opinions welcome.
