In the 100 yards or less flat shooting hunting world, pie plate accuracy is fine. Grab that 30-30 Lever gun and call it good, you'll probably come home with meat. Now consider the following example:
You're on a hunt, you see a big Muley across a 100 yard ravine and 75 yards up the hillside near the top of the ridge and he's looking like he's going over the top. To make matters worse, there's a 10 mph cross wind. You either take the shot of you loose the opportunity. How important is it that your rifle shoots 1 MOA now? I would say it's pretty important and pie plate accuracy is not going to cut it. You've got windage and elevation holds to deal with and you're not going to be 100% accurate with that so you're depending on your rifles accuracy to get you through it.
Just so you know, that situation occurred in 1963 in the Ruby Valley of Nevada, I was 10 years old with my first rifle, a 1963 model 94 30-30. I got the buck on the 5th shot and on the run and yes it was pure luck by a kid with buck fever. My Dad made sure I knew that I should have never taken the shots but around the campfire that night he had bragging rights and made good use of them.
