Barnes Bullets TSX 7mm .284 140gr Boat Tail Reloading Bullets - 50/Box

The Barnes Bullets TSX (Triple-Shock X) Boat Tail is a premium all-copper hunting projectile aimed at handloaders seeking serious accuracy and deep penetration. This 7mm / .284 bullet weighs 140 grains and is built around a solid copper jacket over a copper core, with no lead core. Barnes' all-copper construction is engineered to virtually eliminate fragmentation and produce roughly 28% deeper penetration than conventional lead-core bullets on impact.

Multiple precisely machined grooves cut into the bullet's bearing surface initiate reliable, controlled expansion across a wide velocity range, while the hollow point tip drives consistent, predictable upset. A cannelure on the shank lets the handloader seat the bullet firmly in the case mouth without distorting the bearing surface. The tapered boat tail base reduces drag and lifts the bullet's ballistic efficiency, helping produce a flatter trajectory and better retained energy downrange.

For handloading, this TSX BT lists a ballistic coefficient of .394 and a sectional density of .248, with an overall length of 1.265". Sized for any 7mm case neck (0.284" bullet diameter), it is recommended for hunting applications. Barnes provides published load data for this projectile in 7mm Remington Magnum, making it a proven choice for handloaders building hunting ammunition. Each box contains 50 projectiles, ready to load.
