Oh, no question that more accuracy = better, and if you can obtain more accuracy, by all means, get more.I absolutely agree with this. In reality inside of 300 yards 1 - 3 MOA for a single shot, is still a hit on most "targets". That said guns are kind of like cars, no one needs a 10 second 1/4 mile car, millions of people drive and are completely functional with 18 second cars, but it doesnt mean people dont want a faster one =)
The problem is when you're so invested in the concept that you're not really honest with yourself about what you've got. And, to be fair, this isn't a problem limited to precision shooting... people really kid themselves about the modern viability of older firearms all the time. For example, I know I love the Uzi's iconic looks and reliability (with FMJ), but good luck running that thing competitively at a USPSA match. It's just not as good as modern guns.
