This is more of a question than a statement. However, I seem to remember that in subsequent years, Aagard settled on the 7mm-08 as his favorite. I don't remember him ever repenting his opinions on other chamberings, but 7mm-08 IIRC was his final favorite.
Nope. He played with the 7-08, but as John says, the 308 Win was where he settled. In fact, his last article published posthumously, was on the 308 Win.
