Get the latest issue of Rifle magazine. There's a pretty good article in it that addresses this very subject. I'm not 100% in agreement with the author, but then again I rarely agree 100% with anybody- but he covers the basics pretty well.
I will have to look at that... who is the author?
Gil Sengel. Like I said, pretty fair article, but I got the feeling he isn't a pro in the strict sense of the word, but more a good reporter on the subject.
