This is subsonic ammunition built for today's suppressed rifle setups. Fort Scott Munitions loads these rounds to 960 fps, right where you want them to stay under the sound barrier when paired with a suppressor. The real story is what happens when the round hits its target.
The 190-grain solid copper projectile is engineered with their multi-patented Tumble Upon Impact design, which works differently from traditional hollow points. Instead of expanding on contact with skin, the bullet travels straight through and enters the tissue, then begins to tumble end-over-end. This creates massive internal wound channels by cutting through vital areas rather than relying on surface expansion. The solid copper construction means no lead, and the bullet retains over 95% of its weight after impact. These rounds are loaded in reloadable brass cases, so you can reload them when you're ready to stretch that investment.
Each bullet is precision-machined on CNC lathes with tight tolerances, which carries through to consistent accuracy on target. Customers consistently mention the clean burning and reliable function through suppressors, plus surprisingly quiet operation even in that subsonic velocity range. The load uses Accurate 1680 powder at 10.7 grains, engineered for smooth performance out of typical 16-inch barrels with 1:7.5 twist rates.
This load is commonly used for hunting medium game, home defense, and precision rifle work where reduced noise matters. The heavy bullet weight helps maintain energy at distance compared to lighter subsonic loads, keeping accuracy and performance consistent out to realistic hunting ranges. The subsonic nature makes it ideal for areas where noise is a concern or where you're running a can.
Yes, this load is designed to cycle properly with or without a suppressor. It's built specifically as a subsonic round, so it functions well across most 300 Blackout platforms. Many owners report particularly smooth operation with suppressors attached, making these rounds one of the quieter options on the market for suppressed 300 Blackout setups.
This ammunition typically remains accurate and effective out to 200 to 300 yards, depending on your rifle, optics, and shooting conditions. The heavy 190-grain bullet helps maintain energy better than lighter subsonic loads at distance, which is one reason it's favored for hunting. Barrel length affects velocity, so a longer barrel will perform better at extended ranges than a short-barreled rifle.
TUI bullets don't expand on impact like traditional hollow points. Instead, they travel straight through skin into the tissue, then begin tumbling end-over-end once they hit water-based tissue. This tumbling action creates large internal wound channels by cutting through vital areas. The solid copper construction means the bullet retains its mass and penetrates deeply while maximizing internal damage.
Yes, Fort Scott Munitions loads these rounds in reloadable brass casings, so you can reload them when you're done. This makes the per-round cost more economical over time if you already have reloading equipment and experience.
