My Finnish-made Savage Model 2400's rifle barrel is in .222 Remington.
It works fine for medium game like coyotes and javelina, or for small deer at close ranges. I haven't tried it yet with feral hogs, although some of my hunting buddies tell me it should do the job just fine ("IF you can shoot!).
The 2400 itself is incredibly accurate. But it isn't self-aiming....
