I had a brief correspondence with him 20-odd years ago, relative to an article he wrote about the "inherent inaccuracy" of the .257 Roberts cartridge, regardless of rifle brand, action type, barrel, rifling twist, etc. Pre-Internet, so I had to write him an old-fashioned manual letter. Sent him targets and everything, just to make the point that even in my old, short-action long-throat SUCKS 722 the Roberts accuracy was far more than adequate. His basic response was that no amount of evidence would change what he knew to be right.
The ancient Greek philosophers called it "hubris".
