A: Hi Steve and welcome. No Really, they 40 fps slower and just optimized for lower recoil and noise signature over standard loads. Details here : https://winchester.com/Products/Ammunition/Handgun/Super-Suppressed/SUP45

A: I believe its just a marketing name like the Winchester "Super X" This is their description of the round.... Features: Noise Reduction: The rifle round pushes velocities below the speed of sound, resulting in lower decibel levels. This reduction in noise is essential for maintaining stealth and minimizing disturbance. Decreased Fouling: The copper jacket encloses the base of the bullet core, reducing lead fouling in barrels and suppressors. This feature helps keep your firearm cleaner during extended shooting sessions. Recoil Mitigation: The Super Suppressed line is engineered to minimize recoil, allowing for more comfortable shooting experiences.

A: A little parachute comes out of the back to slow it down. Also, Winchester gives a muzzle velocity of right at the standard ~850fps. I believe their main Super claim beyond marketing is that they used fully encapsulated bullets to be slightly cleaner than regular FMJ's exposed lead base.

A: All "normal" 45 apc is sub sonic. Just the name.
