How do you know you can get a shot at 100 yards or less?
I have killed plenty of elk with shots less than 100 yards. But why would you want to limit yourself? If that cow is out there at 150 yards and that is as close as you can get, you could very well be under gunned with a 20 ga. At 200 yards you would under gunned for sure.
Again I ask, why would you want to limit yourself?
Take the 30.06 and the .270 as a backup. Take the 20 ga and use it to hunt the timber during late morning or early afternoon. The 20 ga would make a great brush or timber gun.
