The .45 pairs the .45 cartridge with a 305gr Punisher projectile in a dependable subsonic load. Genuine, in-stock and ready to ship, this .45 is built to deliver consistent, reliable results from your rifle every time you pull the trigger. Specifications Caliber .45 Bullet weight 305gr Projectile Punisher Type Subsonic Case Factory-new brass Quantity 20-round box The Punisher bullet At the heart of this .45 is the Punisher, chosen to match the subsonic role this load is built for. It is loaded on factory-new brass to consistent tolerances, the foundation of both reliability and accuracy. That round-to-round consistency is what lets the load shoot to the same point of impact shot after shot — exactly what you want whether you are hunting, training or competing. Quiet, suppressor-friendly performance This .45 is loaded subsonic, staying below the speed of sound so it shoots genuinely quiet through a suppressor with no sonic crack. The heavier bullet carries solid close-range momentum while keeping the report and recoil low. It is an excellent match for a suppressed setup where low noise matters most, and a pleasant, hearing-friendly round to shoot all day. What it is best for This .45 suits quiet, suppressed shooting, close-range hunting and comfortable practice. Match the load to your task, confirm your zero before you rely on it, and it rewards you with dependable performance. Different loads print to different points of impact, so always verify your zero with this specific round. For help choosing, read our 300 Blackout vs 5.56 guide.
