Ok, this may sound like overkill but...
how would a .270 wsm be?
It's got the power. But I promise a .25-06 is about as much recoil as you'll want to tolerate shooting rats or rockchucks all afternoon from a prone position. I've taken my .30-06 and fired the same 110 grainers you'd be using in the .270 WSM at about the same velocity, and it becomes quite bothersome after 20 or 30 rounds. And that particular '06 is in a choat stock and weights about 11 pounds.
