I'm really surprised no one has suggested putting a muzzle brake on whatever 30cal you might choose. I'd say get a good 308 and put a muzzle brake on it. It will recoil about like a 22 magnum if you shoot light loads in it. Accuracy will not be affected and components are easier to find. Some are going to say the brake will be a headache to keep clean. That's not my experience.......
Really, this is a good idea for low recoil and accuracy to 200 yds.
