Barnes TSX Bullets .303/7.65mm .311" 150 gr FB 50/ct

The Barnes TSX Bullets .303/7.65mm .311" 150 gr FB ammunition represents a premium choice for reloaders and shooters working with military rifle cartridges, particularly the .303 British and European military calibers. These all-copper, lead-free projectiles are engineered for controlled expansion and maximum weight retention—critical factors when terminal performance and shot reliability matter in the field.

The 150-grain weight in the .311" diameter sits at the middle of the performance envelope for .303-class rifles, balancing velocity retention and energy transfer across typical hunting and precision-shooting distances. The flat-based (FB) design—as opposed to boat-tail—maintains consistent ballistics in short-range applications and delivers predictable terminal performance on game. Each round is manufactured from 100 percent copper with Barnes' proprietary expanding design, which creates four razor-sharp cutting petals upon impact while maintaining structural integrity through bone and dense tissue. The ammunition retains 100 percent of its original weight, eliminating fragmentation that could waste energy or reduce penetration reliability.

This 50-round box format is ideal for serious handloaders working with .303 British, 7.65x53mm, and comparable military rifle cartridges who demand consistent, premium projectiles. Reloaders value Barnes TSX bullets for their dimensional consistency, which supports tighter shot grouping and repeatable accuracy across multiple loads. Whether you're loading for vintage military rifles, modern sporting reproductions, or precision-rifle applications, these bullets deliver the terminal authority and weight retention that differentiate premium ammunition from commodity options.
