It duplicates the .17 Hornet. It will work in areas where they restrict centerfire guns during certain seasons. Personally I'll stick with the .17 Hornet, Alaska has restrictions against rimfire guns being used for certain game. Depends on where one lives as to whether they can us one or not. The guns will most likely not show up till after production of other higher profit guns are caught up on. Same with the ammo. Since most gun makers are over a year behind on orders, this new gun most likely will not show up till things get caught up. From what I read Savage just modified up their .22 mag bolt gun, to handle the new cartridge.
