RE: How accurate do you feel you need to be?
Thats what makes the world go 'round.....variety. Just because I'm a accuracy nut doesn't mean that its suited for everyone. I get a certain amount of enjoyment from making rifles as accurate as I can with my skills, but that isn't suited for everyone.
Can you kill a deer/elk/whatever with a 2+ MOA gun? Certainly. Would I carry that same weapon in the woods? Never. Can I shoot a sub 2 MOA group offhanded at 100 yards without the benefit of a sling? NOT BLOODY LIKELY. With a sling, on a calm day, with plenty of time I think I could shoot a 4 inch group offhanded at 100 yardspretty consistantly. But, I only shoot offhanded as my last options and only if its a very reasonable distance.
