Ballistic Performance and SAAMI Specifications

Federal manufactures every round in this line to SAAMI’s published specifications for the 45 ACP cartridge. This ensures safe chamber pressures and reliable dimensional compatibility with SAAMI-spec firearms. For example, handloaders working up their own 137 grain projectiles often reference this factory loading’s published velocity as a useful benchmark. However, chronograph results can vary by barrel length. Therefore, always verify velocity and function in your own firearm before relying on this load for defensive or competition use.
