The .460 Rowland Ammo is a proprietary cartridge that captures the true level of velocities of the .44 Magnum Ammo when chambered into several popular semi-automatic rifles, pistols, and revolvers. The .460 Rowland Ammo was designed and developed in 1998, and the cartridge is manufactured to this day. The .460 Rowland Ammo is 1/16th longer than a traditional .45 ACP Ammo to prevent the high pressures .460 Rowland Ammo from being used with a standard chambered firearm for the low pressured .45 ACP Ammo. There are two main aspects to this cartridge. A sharp increase in the maximum pressure of the bullet casing over the .45 ACP Ammo and .45 Super Ammo.
