Tom,
John Snow has been the shooting columnist for OL since Jim Carmichel retired in 2008. He was a pretty experienced shooter and hunter before then, but because of his job has gained a lot more since then.
Hard to follow in Jim's footsteps....but he hasn't done too badly.
Jim is the reason I got myself a .280 Mountain Rifle in the 80's.
That being said, everyone already knows that the .308 Win is the greatest rifle cartridge in the universe.
