The CZ 550 FS has a 20.5" hammer forged barrel, 9.5" twist, with a reamer cut chamber. It is longer than a carbine, shorter than many rifles, perfect for the gun's 9.3x62mm Mauser cartridge, where appropriate powder selection will result in a 99% burn. Consider the CZ 550 barrel is a half inch longer than the barrel Ruger selected for its Alaskan model, where the 375 Ruger cartridge has a capacity 30 grains greater than the 9.3x62mm. The FS is compact at 40 1/2" overall, or approximately 6" shorter than my CZ 550 Safari. At 7 1/2 lbs the FS is also about 1 3/4 lbs lighter.
