CZ 455 is definitely out to rule the deluxe rimfire market in the USA.
You have Anschutz/Weatherby/Sako Quad for the deep pocket crowd, and the Savage/Marlin range for the not-so-deep pocket crowd.
CZ 455 will shoot it out with Ruger M77/22 for that big middle price range, where performance and cost are balanced rather well..
Ruger10/22, of course, lives in its own world.
