Fort Scott Munitions TUI 260 Remington ammo uses a machined solid copper projectile engineered to tumble end-over-end upon contact with water-based tissue, creating wound cavities larger than the bullet diameter without relying on expansion or fragmentation. At 130 grains and 2922 fps from a 24-inch barrel, this load delivers 2464 ft-lbs of muzzle energy and maintains a G1 ballistic coefficient of 0.566 for flat trajectory work at hunting ranges. The 260 Remington — a necked-down .308 Winchester case pushing 6.5mm projectiles — sits between .243 Winchester and 6.5 Creedmoor in chambering popularity, offering lighter recoil than larger 30-caliber rounds while carrying enough sectional density for medium game. Fort Scott Munitions CNC-lathes each solid copper projectile to tight tolerances, eliminating the jacket-core separation common to cup-and-core bullets. Lead-free construction complies with condor range mandates and non-lead hunting regulations in effect across California and select Western public lands.
Built for the Box
Each TUI projectile starts as a solid copper rod machined on a CNC lathe — no swaging dies, no jacket bonding, no core pour. The patented Tumble Upon Impact geometry places mass forward of center, causing the bullet to destabilize and tumble longitudinally when it encounters the hydraulic resistance of tissue. This tumbling action shears a wound channel 3-4 times the bullet diameter without bullet weight loss or fragmentation. Solid construction means no petal shear, no jacket slip, no core separation. The copper alloy retains 100% of fired weight through bone, muscle, and hide. Boxer-primed reloadable brass cases arrive ready for fire-forming to your chamber, and the non-corrosive priming mix extends shelf life in humid or high-heat storage. Rated supersonic across typical hunting distances, the 130-grain TUI holds velocity and energy downrange better than lighter varmint pills while producing less barrel wear than heavy magnum loads.

The 260 Remington competes directly with 6.5 Creedmoor in long-range bolt-gun applications, and this TUI load suits whitetail, mule deer, pronghorn, and feral hog hunts where non-lead projectiles are mandated or preferred.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Follow the four rules of firearm safety: treat every gun as loaded, never point at anything you’re not willing to destroy, keep your finger off the trigger until ready to fire, know your target and what lies beyond it.
- Verify current state and local ammunition laws in your jurisdiction — some municipalities restrict lead-free or solid projectile ammunition types.
- Match ammunition to your rifle’s chamber specifications. 260 Remington headstamps must match your barrel stamp exactly — do not mix calibers.
