The CZ 457 American in 17 HMR chambers the flat-shooting, wind-bucking 17 Hornady Magnum Rimfire cartridge in the classic American walnut sporter configuration. The 17 HMR's 2,550 fps muzzle velocity and explosive 17-grain V-MAX bullet make this the longest-range practical rimfire in the 457 lineup. The 457's cold-hammer-forged barrel extracts full accuracy potential from this high-velocity cartridge.
