The Tumble Upon Impact® (TUI®) Bullet Design
The TUI® (Tumble Upon Impact®) is Fort Scott Munitions’ multi-patented terminal mechanism — fundamentally different from both expanding and fragmenting bullets. The solid copper projectile is engineered to destabilize and rotate approximately 90 degrees after 1–2 inches of penetration into soft tissue, presenting its full length broadside to the wound channel. This creates a large effective cutting diameter without requiring hydraulic expansion.
Because the bullet is monolithic solid copper, it retains ~100% of its weight throughout the terminal event — no lead core to separate, no jacket to peel. The tumbling mechanism does not depend on minimum impact velocity thresholds the way hydraulic expansion does, making terminal behavior theoretically more consistent across varying ranges. The SCS® (Solid Copper Spun) projectile is machined from solid copper bar stock on CNC lathes to extremely tight dimensional tolerances.
Best Uses
Good fit:
- Deer, pronghorn, and feral hogs where deep penetration and near-100% weight retention are priorities
- California and any other lead-free jurisdiction — fully non-toxic, Condor Zone compliant
- Hunters who want consistent terminal performance across varying impact velocities — TUI does not require a minimum velocity threshold unlike hydraulic expansion
- Shooters who prefer a unique terminal mechanism (tumbling) over conventional expansion or fragmentation
Not the right tool for:
- Hunters who need a published and independently verified BC for precise long-range firing solutions — the velocity discrepancy between sources adds uncertainty
- Indoor ranges that prohibit hard copper solids — verify range rules before use
- Varmint hunting where rapid shallow fragmentation is preferred
Reliability Notes
No structured submissions yet.
Fort Scott Munitions is a US-based manufacturer (Hays, Kansas) producing ammunition for civilian, law enforcement, and military markets. The SCS® bullet is machined on CNC lathes from solid copper bar stock — a manufacturing process Fort Scott states produces exceptional dimensional consistency and concentricity. No active recalls or lot-specific issues have been identified. The velocity discrepancy between published sources (2,782–3,026 fps across retailers vs 2,933 fps in Fort Scott specs) is documented and warrants community chronograph data for resolution. All notes reflect manufacturer claims and open-source information, not structured data.

FAQ
What exactly does “Tumble Upon Impact” mean?
The TUI® projectile is engineered to penetrate straight for the first 1–2 inches of tissue, then destabilize and rotate approximately 90 degrees — presenting its full length broadside to the wound channel. This is fundamentally different from a hollow point that expands radially or a fragmenting bullet that sheds petals. The tumbling mechanism does not depend on minimum velocity thresholds, making it theoretically consistent across the full hunting range. The solid copper construction means ~100% weight retention throughout.
Is this load California-legal for hunting?
Yes. The SCS® bullet is machined from solid copper with no lead content, qualifying as non-toxic ammunition under California DFW statewide lead-free requirements and Condor Zone restrictions. Always verify current California DFW regulations before the season.
TUI 123 gr vs TUI 130 gr — which should I choose?
The 123 gr has slightly higher muzzle velocity but lower BC (0.510 vs 0.566 for 130 gr). The 130 gr carries more energy at all ranges and bucks wind better beyond 300 yards. For deer and pronghorn inside 300 yards, either works well. For longer shots or windier conditions, the 130 gr’s higher BC provides a meaningful advantage. See the separate 130 gr report for side-by-side comparison.
Why do different retailers list different velocities for this load?
This is a genuine data inconsistency. Fort Scott’s product page has shown 3,026 fps; their specifications document lists 2,933 fps; some retailers list 2,782 fps. The discrepancy likely reflects different test conditions, barrel lengths, or updated lot specifications. Fort Scott tests at 24″ barrel with 1:8″ twist — shorter barrels will show lower velocity. Community chronograph submissions on this page are the most reliable way to establish actual field velocity across different barrel lengths.
Can the brass cases be reloaded?
Yes — brass cases with Boxer primers are fully reloadable. Fort Scott recommends Hodgdon Superformance or StaBALL 6.5 powder. COAL range: 2.760″–2.800″. This page covers factory ammunition only — consult published reloading data for solid copper bullet load development, which typically differs from jacketed lead-core loads.
