Barnes Bullets TTSX Features The Barnes TTSX bullet is a 170 grain .284 inch diameter projectile engineered specifically for fast-twist 7mm cartridges making it one of the heaviest tipped copper bullets available for this caliber. Reloaders working with a 1:8 inch twist rate barrel will find it stabilizes reliably while still offering forgiving performance across different seating depths and powder charges. The front TSX groove is optimized around the 7mm PRC cartridge but the bullet s .721 inch nose length gives it broad compatibility with most other 7mm chamberings sharing the same twist requirement. This flexibility lets handloaders use one bullet across multiple 7mm rifles without sacrificing accuracy or stabilization. As an all-copper design the TSX-pattern bullet is built for weight retention and deep consistent penetration characteristics that Barnes has built its reputation on in both hunting and precision-oriented projectiles. This component ships 50 to a box strictly for handloading and is not a loaded cartridge so reloaders will need to supply their own brass primers and propellant to complete a finished round. Careful attention to seating depth is recommended given the bullet s extended nose length relative to lighter 7mm projectiles. For handloaders chasing accuracy and heavy-for-caliber performance in a 7mm rifle the Barnes TTSX 170 grain bullet is a purpose-built option worth loading.
