That's about as subjective as you can get, too - depends where you are. M1 carbine ammo you can look for till you're blue in the face in, say, Northern Holland, Burma or Leningrad!
Also, the M1 carbine wasn't very good at actually killing people - didn't they find that out the hard way during the early part of the Korean War?
