So, a long time ago (1996 or 1997), I had made a statement to a friend that "If it's on the Internet, I can find it." This was back when Lycos and Webcrawler and AltaVista were the best search engines. He challenged me to find out how much a bullet fired from an M-16 dropped at 500 yards (back then, it took me 45 minutes to find). He was ex-Marine, so this was information that he already knew.
So, I used that same concept to test your theory. My exact query was:
-- how far will a bullet drop at 500 yards
The Google results were very heavily weighted to a 308. The Bing results included multiple caliber rounds. I think the Bing results are more comprehensive for this query and it is sufficiently non-simple.
I'm sure there are plenty of queries where Google is better, but there are also queries where Bing is better. Which is why I use every tool available to me.
