Barnes Bullets 30700 .510 Caliber 647 Grain TSX Boat Tail Bullets, 20 Count

Barnes Bullets part number 30700 TSX Boat Tail bullets are designed for .50 BMG reloading applications and hunting use. Each .510 caliber projectile features a 647-grain all-copper construction that delivers reliable weight retention and deep penetration without the fragmentation associated with traditional lead-core bullets. The hollow point design is engineered to support controlled expansion when used in suitable hunting loads.
The TSX design incorporates multiple precisely engineered relief rings along the bullet shank. These rings help reduce friction and pressure as the bullet travels through the bore, supporting improved accuracy, reduced copper fouling, and the potential for higher velocity loads when developed in accordance with published reloading data. A boat tail profile further supports stable flight and consistent external ballistics.
With a .572 ballistic coefficient and .355 sectional density, these Barnes TSX bullets are suited to reloaders seeking a durable, lead-free projectile for large-caliber applications. The copper solid core, copper solid jacket material, and cannelure contribute to the bullet’s robust construction and consistent performance. This package contains 20 bullets and is intended for experienced reloaders who follow current, verified load data and safe ammunition-handling practices.
