Although a novice with all of this, my recently-acquired LE Jungle Carbine (in .303) would be my choice. To put this in context, I've never yet hunted or been all that far from civilization, and so my preference and views are worth nothing.
But the combination of the Jungle Carbine's light weight/portability and its power really appeal to me.
This occurred to me even before seeing the superb photo posted by experienced (LE etc) shooter, Mr. Tikirocker. He would be my LE guru and it's a shame for some of us that he does not live over here in the Mid-south. Gun store staff here seldom if ever see any Lee-Enfield.
Asking them about such rifles and surplus ammo on the phone surprises them, as if they were asked whether they speak Russian.
