I haven't had experience with any of the cartridges mentioned in the original post, but I've used a Model 20 in .308 for elk hunting a couple of times during the last seven or eight years. I'm not a long-range hunter, but my rifle has worked well at ranges a little over 300 yards. Never shot a deer with the NULA, but I've used the .308 cartridge in other rifles for deer hunting.
The 3" magazine length of the Model 20 has proven to be an advantage in that my favorite load gets best accuracy by seating the bullet to an OAL too long for the magazines in most other .308-length actions.
