Barnes TSX Flat Base Bullets in .450/400 caliber (brand part no. 30514) bring the original Triple-Shock X design to this classic dangerous-game double rifle cartridge. TSX bullets are machined from solid copper with no lead core, and Barnes cuts a series of rings into the bullet’s shank, a patented feature that reduces bore friction and pressure while improving accuracy compared to a smooth-shank monolithic bullet. The hollow point nose is engineered for controlled expansion and near-complete weight retention on heavy game, and the flat base is the traditional profile .450/400 double rifles are built around. This is a proven, dangerous-game-grade bullet for handloaders working up ammunition for a .450/400 rifle.
