Ballistic Performance and SAAMI Specifications

Underwood manufactures every round in this line to SAAMI’s published specifications for the 40 S&W cartridge. This ensures safe chamber pressures and reliable dimensional compatibility with SAAMI-spec firearms. For example, handloaders working up their own 200 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.
