Sure, I’d grab an AR first, but I like the little M1 Carbine. My pick is based on just about everything I’ve read: the 110gr soft point would be the ticket. I recall reading that either GKR or Fackler said the Remington 110gr SP was equal to a .357 Magnum 158gr SP from a handgun. If that’s the case I’ll take it!
I also keep a lot of 110 grain soft nose on hand for the same occasion. I do remember reading somewhere of the fitness of the 30 cabine with a soft nose bullet. On par with the 357 magnum.
