CZ makes a 22-250 varmint weight barreled rifle which might fit your needs. It is the CZ550V. To my knowledge they chamber it in 308 and 22-250. I have not tried the 22-250, but I own and love the 308. It is a very high quality firearm with many features, but the neat thing is it has a detachable box magazine, and will accept the 10 round CZ 750 mags, which, on a hot prairie dog town might be a benefit.
A couple 10 round magazines would really extend the shooting as you come over a rise into a swale where nobody has ever shot at the big old fat rodents.
To my way of seeing things, it is so much better than any Remington 700 I have owned. It might be worth checking into.
