I thought about this quite a bit while hunting in CO for the second rifle season. Most would agree that 90% of shots on game are at 100yds or less in the US. Elk often are in the thick stuff ie. close ranges.
How many of you would be satisfied with a 3-4 MOA hunting rifle. Not me, but if you are sighted in 3-4 inches high, you are intentionally going to have an bullet impact 3-4 inches from your point of aim for 90% of your shots!
I leave all my guns sighted at 100. Most traditional center fire cartridges will only drop 3-5 inches out to 200 when zeroed at 100. For longer shots you have more time to adjust (click, holdover, ect.) For the close and quick shots I want my bullet going right where I aim. I also like to take a headshot when possible on relaxed close game (deer). A 100 yd zero makes this easy�..that could start a whole new unintentional debate.
Just my thoughts on the subject, but I am not an �expert�.
