The part that you do not understand, is just what Hal said. In the big picture, Remington 700s have, and still do, outsell the brands you mentioned. They are still the most popular choice among hunters, law enforcement, and military, like it or not. They are also still the favorite factory action upon which to build a custom target/varmint rifle upon, and the choice of top gunsmiths who specialize in such builds. The 700 is also HIGHLY copied and MANY clones/customs based on it exist.
I'm about done here. If you want to fantasize that hunters, target shooters, top gunsmiths, law enforcement, and military ALL choose Remington because they simply don't know any better, go right ahead. I'll stick to reality........
