Ballistics Table – 100-Yard Zero

Official muzzle data only. The manufacturer does not publish a SKU-specific ballistic coefficient or downrange table. To avoid guessing, the requested 25-yard rows through 300 yards are shown as Not calculated. The 100-yard zero is identified, but no trajectory is fabricated. No wind column is shown.

Key takeaway: This table is a trajectory reference under the stated conditions, not a terminal-performance test or a recommended maximum hunting range.

The TUI Bullet — What “Tumble Upon Impact” Actually Means

Fort Scott describes TUI as tumbling after contact with tissue or water, not tumbling during normal flight. A guaranteed 90-degree turn or velocity-independent performance for this exact load was not verified.

The manufacturer identifies an all-copper, lead-free projectile. That material description alone is not a legal certification; check the current approved-ammunition list and rules for the particular location and season. The absence of a hollow point does not establish legality or suitability for a defensive application.

Best Uses

Good fit:

• Hunting medium to large game (deer, feral hog, black bear) at ranges inside 150 yards where the trajectory arc is manageable
• The manufacturer identifies an all-copper, lead-free projectile. That material description alone is not a legal certification; check the current approved-ammunition list and rules for the particular location and season.
• The product description does not establish defensive effectiveness or jurisdiction-specific legality
• The product description does not establish defensive effectiveness or jurisdiction-specific legality
• Hunters who want maximum weight retention and deep penetration on heavily muscled or thick-skinned animals

Not the right tool for:

• Downrange predictions requiring a verified BC; no official BC was found for this load
• Varmint or thin-skinned game where over-penetration is a concern — the solid copper construction and tumbling mechanism are designed for deep penetration, not rapid energy dump
• Budget-conscious shooters doing high-volume practice; at its premium per-round cost, this is a hunting or defensive load, not a range trainer
• Rifles with very short barrels (guide guns under 18″) where velocity loss may reduce the margin of consistent TUI tumbling initiation, though FSM does not publish a minimum velocity threshold

Reliability Notes

No structured submissions yet.

Fort Scott lists 1,763 fps from a 24-inch, 1:20-twist barrel. The 20-round web variant is SKU 758381721396-0, UPC 758381721396. Official muzzle energy, BC and downrange data were not verified. The manufacturer warns against use in revolvers. No structured, load-specific reliability test is presented here. Component details or general reputation should not be treated as proof of feeding, accuracy or absence of defects.

Competitors

Barnes VOR-TX 45-70 Government 300 gr TSX FN and Fort Scott SCS TUI 300 gr use copper projectiles with different described mechanisms: TSX expands, while TUI is designed to tumble after tissue contact. A fixed tumbling angle or matched performance ranking was not verified.
