I have the NEF with the .223 heavy and .308 heavy and the .50 muzzle loader. The .308 is a tack driver 1/2 to 3/4 at 100 yards. The .223 I have yet to find a good load for. I'm getting about 1 to 1 1/4 with handloads and most factory shoots about the same. I've killed 3 elk with the .50 so I'm happy with that.
