Fort Scott 223 Rem 55gr TUI Solid Copper – Reliable 20 Round Box

Description

The Fort Scott 223 Rem 55gr TUI load is a 20 round box of 223 Remington ammunition from Fort Scott Munitions, an American company in Fort Scott, Kansas. It uses a 55 grain Solid Copper Spun (SCS) bullet with the company’s Tumble Upon Impact design, and Fort Scott lists a test velocity of 3,211 fps from a 24 inch barrel with a 1:7 twist.

Fort Scott 223 Rem 55gr TUI Overview

A 55 grain bullet is the classic 223 Remington weight, and Fort Scott’s solid copper version brings it to a lead-free design that tumbles on impact. Tested at 3,211 fps from a 24 inch barrel, it shoots flat for varmints and predators while the tumbling action delivers more effect than a simple full metal jacket. Because it relies on tumbling rather than fragmentation, it holds together, which is useful for hunters who want to avoid lead fragments and for home defenders who want consistent penetration. AR-15 owners also appreciate that it can be used where lead projectiles are restricted.

How TUI Works

Fort Scott’s patented Tumble Upon Impact (TUI) design works differently from an expanding hunting bullet. Rather than mushrooming, the lathe-turned copper bullet is engineered so it begins to yaw and tumble shortly after it enters a target. A tumbling bullet presents its full length as it travels, creating a large wound channel while retaining its weight because it does not fragment or shed petals. That means deep, consistent penetration and no lead fragments in game meat.

Non-Lead Construction

Because the bullet is a single piece of copper turned on a lathe, it contains no lead core. That makes it compliant in areas that restrict lead ammunition for hunting and reduces lead exposure at the range. Monolithic bullets are longer than lead-core bullets of the same weight, so Fort Scott tunes seating depth and powder charge for each load.

Firearm Compatibility

Fire this ammunition in rifles chambered for 223 Remington, 5.56 NATO or 223 Wylde. Fort Scott tested it with a 1:7 twist; solid copper bullets are longer than lead-core bullets of the same weight, so very slow twist barrels such as 1:12 may not stabilize it well. Test accuracy in your rifle before relying on it. Never use it in a 300 Blackout firearm.

Accuracy and Testing

Every rifle has its own preferences. Before you hunt with this load, fire several groups at your usual distance to confirm point of impact. Solid copper bullets often shoot to a different point than lead-core ammunition of the same weight, so a fresh zero check is always worth the time, and clean copper fouling from the bore if accuracy starts to drift.

Recoil and Shootability

Recoil from a 223 Remington rifle is very light, which makes it easy to practice with and comfortable for new shooters. Short barrels will produce lower velocity and more muzzle blast than the 24 inch test barrel.

Made in the USA

Fort Scott Munitions designs and manufactures its bullets and loaded ammunition in Kansas. The company holds patents on its tumbling bullet technology and offers it across a wide range of handgun and rifle calibers.

Storage and Care

Store ammunition in a cool, dry place in its original box, away from solvents and lubricants. Inspect cartridges before use and set aside any with dents, corrosion or loose bullets.
