Description
Fort Scott Munitions built their reputation on taking the copper bullet concept seriously, and these 5.56 NATO rounds showcase exactly why. Each cartridge uses a 70-grain solid copper spun projectile machined from solid copper rod on a CNC lathe. There's no jacket, no lead core, just precision engineering from end to end. The bullets feature multiple driving bands that help with both accuracy and bore fouling, and the whole thing is loaded to match-grade standards with tight velocity consistency.
What Makes the 70gr TUI Different
The real innovation here is Fort Scott's Tumble Upon Impact (TUI) technology. When the bullet hits soft tissue, it doesn't just punch a straight hole and stop. Instead, it flips end-over-end through the tissue, creating a much larger temporary wound channel than you'd get from a conventional projectile. This happens without the bullet fragmenting or losing its integrity. Third-party testing has shown these rounds retain over 95% of their original weight even after impact, which means you get penetration alongside that tumbling action. Independent reviews noted the round demonstrated significant yaw within short distances and created very large temporary wound cavities. Real-world field results have been impressive too, with hunters consistently reporting quick, clean kills.
Performance You Can Count On
Muzzle velocity runs 2874 feet per second from a 24-inch barrel, and the ammunition leaves the factory with extraordinarily tight tolerances. The solid copper construction means there are no moving parts to worry about, unlike traditional jacketed bullets where the jacket and core can separate. Every round coming out of the box performs the same as the last one. The non-lead construction also means this ammo works in sensitive areas and won't raise concerns about environmental impact. For those hunting in regions with lead-free ammunition mandates, this rounds the box easily.
Whether you're running an AR platform, running competitions, or hunting game from deer to hogs, these rounds deliver the accuracy and consistency you expect from match-grade ammunition.

Frequently Asked Questions
What is Tumble Upon Impact (TUI) technology?
TUI is Fort Scott's patented bullet design that causes the projectile to flip end-over-end when striking soft tissue, creating a larger wound channel than conventional bullets. The solid copper construction means the bullet maintains over 95% of its weight through impact, combining penetration with this tumbling action for devastating terminal performance.
Is this ammunition suitable for hunting?
Yes, absolutely. The 70-grain solid copper bullet combined with TUI technology makes it effective for hunting deer-sized game and larger. The lead-free construction also makes it compliant with lead-free ammunition regulations in certain states and hunting areas. Velocity, accuracy, and terminal performance are all well-suited to field use.
How does solid copper ammunition compare to traditional lead-core bullets?
Solid copper bullets offer several advantages: no jacket-core separation, superior penetration consistency, environmentally friendly construction, and precise manufacturing tolerances since they're machined from solid rod rather than swaged. The main difference is that solid copper relies on tumbling and hydrostatic shock rather than expansion, making bullet construction and impact design critical to performance.
Will this ammunition work reliably in my AR?
Yes. These rounds are loaded to standard 5.56 NATO specifications with non-corrosive Boxer primers and brass cases. They'll feed and function in any modern 5.56 platform. The driving bands on the bullet help with accuracy and reduce bore fouling compared to some other designs. Independent reviews noted 100% reliability across various platforms.
