Boddington is the man. You gotta love a guy who can appreciate a rifle from all aspects. I mean he is someone who has hunted the world for wild game and enemy third worlders. I love his no non-sense style, and unlike other gun writers, I have even seen him make negative comments about rifles that he does not like. Most writers seem worried about sponsorship and claim to love every piece of junk that can spit out a hunk of lead. Truly a "Great American". Second on the list, though rifles are not his main focus, Jim Zumbo is very good when he comments on his arsenal. And finally, if we expand into tactical weapons, Peter Kohkalis (spelling?). He is very hard to beat on anything battlefield related.
