VOR-TX TSX Flat Base Ammunition delivers handloaded precision in a factory round super-engineered to stop big game in its tracks. A reputation forged from solid copper and epic knockdowns. Expect complete penetration from our all-copper bullet technology with virtually 100% weight retention and double-diameter expansion. It's a flawless confluence of bullet integrity and predictable, bone-busting chaos that puts animals on the ground like nothing else. They're the deadliest and most accurate hunting loads on the planet. Introduced in 2003, the TSX Bullet incorporated horizontal grooves along the circumference of the bullet, which eliminated the need for a dry lubricating film. These grooves also provided a place for copper displaced by the rifling to resettle. This results in reduced pressures and less copper fouling. Reduced pressures mean the bullet can be safely loaded to higher velocities. The rings also alter barrel harmonics, greatly improving accuracy.
