Help deciding on a caliber?

[TMB 1]

.22 Magnum maybe, or .17 HMR.

The bad thing is that rimfire bolt guns usually feel like toys. Cheaply made toys. Besides, you can get Rugers, Savages, Howas, and others in the low 300's.

17 Hornet or 22 Hornet if you reload. Ruger, Savage or CZ not cheap made toys, $500-$800

Based on the goals that you stated, I would also recommend the .223. The ammo is cheap, plentiful, and accurate to 300 yards. Since you are not hunting, power is not a factor. Also, the .223 is a light recoiling rifle.
