I agree that Savages shoot very well. I would say there are no real #1 receiver. Some used are BAT, Farley, Stiller, Kelbly Panda, Surgeon, are the most popular. They are basically Remington clones.
Have to disagree a bit on this, I only own some on this list but my BAT's, Panda's and Viper action's are not Remington clones (perhaps the Surgeon is).
The only thing in common is the TRIGGER design.
