G'day there. This is my first post on this forum. I have read plenty of comments here in the past on various topics and found plenty of good objective opinions. 
I would like to comment on this post as I have had personal dealings with Nathan, have read most of his books and have poured hours of time into reading though the ballistic studies Web pages on cartridges. 
My take is that this guy is an extremely knowledgeable when it comes to terminal Ballistics. When I say terminal Ballistics I am referring to shooting various cartridges, projectiles at live game - not phone books, ballistic jelly or ballistic calculators from a arm chair. 
I am not an expert but just someone keen on walk up hills and and putting meat on the table, and like a lot of you guys I am very passionate (a geek) when it comes to gear, getting out there and things that go bang! In my mind Nathan is the biggest geek out there, a true legend and someone's opinion I take very seriously. 
Take a look and create your own opinion. Cheers, straight powder!
