Shaman, I couldn't help but laugh while reading your post. My B-I-L was 13 years old when I married his sister and he was the little brother that I never had. He started deer hunting not long after that with an old 742 that MAY have been a 4 MOA rifle. His zeroing technique was to shoot at an empty coke can laying on the ground anywhere from 25 to 40 yards away....while leaning over the hood of his truck. If the can moved at the shot, he was good to go. Despite this, he was, and still is, the most prolific deer killer I have ever been around. If he spots a deer, it is dead.

About 25 years ago(I've been hunting with him for 50 years now), I gave him a 308 bolt action because the 742 finally shot to pieces. It is a good rifle capable of 1 to 1.5 MOA, but I can't see any appreciable difference in his deer killing prowess. When you seldom miss with a 4 MOA rifle, how much better can you do with a more accurate rifle?
