Buffalo Bore 460 Rowland 255gr HCFN Handgun Ammo - 20 Rounds - The .460 Rowland is squarely at mid 44 magnum power levels. This means that a person can now carry a 1911 style combat pistol that has the power of a 44 mag. revolver, but is slimmer, faster to reload, faster to shoot and holds nine rounds instead of a revolver's six. This load is simply a 45 ACP case that has been slightly lengthened so it won't chamber in a 45 ACP chamber. It also has a stronger web area in the casing, so as to avoid "blowouts". 20 Rounds Field Proven Maximum Firepower Strictly Big Bore
