It features a stronger case head for higher pressure tolerance, resulting in significantly higher velocities, while maintaining the same external dimensions as .45 ACP for compatibility.

What were the velocity results for .45 ACP and .450 SMC in the test?

In the test, standard 230-grain .45 ACP ammunition averaged around 875 feet per second. The .450 SMC demonstrated much higher velocities, ranging from 1349 to 1377 feet per second, with impressive consistency.

Why is the .45 ACP considered a versatile caliber for competition?

The .45 ACP is valued in competition for its excellent balance of power, accuracy, and speed. It meets power factor requirements, excels in precision shooting disciplines like Bullseye, and can be tuned for both accuracy and rapid firing, making it a 'jack of all trades'.

Can .450 SMC ammunition be safely fired in a .45 ACP handgun?

Yes, the .450 SMC is designed with the same external dimensions as the .45 ACP. This compatibility allows it to be fired in standard .45 ACP firearms, though its higher pressure performance should be noted.
