Barnes .270 Caliber 110 Grain TTSX Boat Tail bullets are premium hunting component projectiles built around the Tipped Triple-Shock X design. MPN 30274 identifies the .277-inch diameter, 110-grain TTSX Boat Tail configuration supplied 50 bullets per box.
The TTSX combines Barnes’ monolithic copper construction with a polymer tip. The tip improves aerodynamic performance and helps initiate expansion, while multiple grooves in the shank reduce bearing surface and support the performance characteristics of the Triple-Shock design.
The 110-grain projectile uses a boat-tail profile and belongs to the standardized .270 Caliber component-bullet family. Its nominal bullet diameter is .277 inch; cartridge designations such as .270 Winchester are kept separate from component caliber.
These are component bullets intended for metallic cartridge reloading and are not loaded ammunition. Each box contains 50 projectiles.
