Fort Scott Munitions Tumble Upon Impact (TUI) 300 Blackout Subsonic 190 Grain Solid Copper Spun Rifle Ammunition 20-Round Box 300-190-SCV1SS
Product Description
If you regularly shoot a suppressed 300 Blackout rifle or pistol, you know how difficult it can be to find subsonic ammunition that delivers both ultra-quiet operation and effective terminal performance. Many traditional heavy subsonic loads rely on basic lead round-nose profiles that leave messy residue behind, or hollow-point designs that struggle to expand reliably at lower velocities. The Fort Scott Munitions 300 Blackout Subsonic Tumble Upon Impact (TUI) ammo solves this common issue with a patented, solid copper projectile engineered to cause massive internal damage without relying on expansion at all.
The core of this premium load is its heavy 190-grain Solid Copper Spun (SCS) bullet. Each monolithic projectile is precision CNC-machined from high-grade solid copper rods to guarantee strict manufacturing tolerances, flawless balance, and excellent weight retention. Because it is completely lead-free, it significantly cuts down on airborne heavy metals and carbon fouling at the indoor range or inside your expensive silencer's baffle stack. Unlike conventional projectiles that mushroom outward, the multi-patented TUI design is engineered to tumble end-over-end upon contact with soft tissue, creating a wide, devastating wound path and transferring its kinetic energy directly into the target.
Traveling at a beautifully managed average muzzle velocity of 960 FPS, these rounds stay safely below the speed of sound to eliminate the loud supersonic crack, providing a comfortable recoil impulse and a quiet shooting experience. While it is highly optimized for suppressed hunting and home security, this match-grade ammunition is designed to cycle reliably in standard semi-automatic platforms with or without a silencer attached, giving you a clean-burning, exceptionally accurate subsonic choice you can depend on.
Each individual factory retail box contains 20 rounds of Fort Scott Munitions Tumble Upon Impact (TUI) Subsonic 300 Blackout 190-grain Solid Copper Spun ammunition.
*Armorer Bench Notes & Safety Guidance: This premium subsonic 300 AAC Blackout ammunition (Part # 300-190-SCV1SS) is legally classified as standard centerfire rifle ammunition but remains subject to state and local compliance regulations regarding online ammo sales in locations like California, New York, Illinois, Massachusetts, Delaware, and Connecticut. Always check your local laws before ordering. This 190-grain monolithic round is optimized for standard 1:7" to 1:8" twist barrels to ensure perfect stabilization at subsonic velocities. If your barrel has previously been used with standard lead-core jacketed or unjacketed ammo, Fort Scott recommends giving the bore a thorough, deep cleaning before shooting solid copper rounds to achieve maximum accuracy and avoid copper fouling issues. Additionally, avoid repeatedly cycling the same unfired monolithic cartridge through your rifle, as the smooth surface of large solid copper projectiles can cause them to slip their factory crimp over time if subjected to repeated bolt slams.
