The Barnes TAC-TX 6mm ARC 90-grain Hollow Point Boat Tail (Barnes part no. 32474) is built around Barnes’ all-copper TAC-TX bullet, a lead-free hollow point designed for controlled expansion and deep penetration without fragmenting. 6mm ARC is a purpose-built AR-15-compatible cartridge developed for long-range performance from a standard-length AR magazine, and pairing it with a monolithic-copper hollow point gives it barrier-blind terminal performance that a traditional lead-core bullet can’t match. Part of Barnes’ VOR-TX ammunition line, this load is aimed at hunters and tactical shooters who want reliable expansion and near-complete weight retention on impact.

Key Specifications

• Chambered in 6mm ARC, a purpose-built cartridge designed to deliver long-range performance from a standard AR-15 magazine.
• The 90-grain bullet weight is the confirmed figure from Barnes’ own product data for this load, and sits on the lighter, faster end for 6mm ARC.
• It’s a TAC-TX bullet, an all-copper hollow point with no lead core to separate from the jacket.
• The all-copper monolithic construction gives it controlled expansion with near-complete weight retention, rather than shedding fragments like a traditional lead-core bullet.
• The boat-tail profile improves the bullet’s ballistic coefficient for a flatter trajectory downrange.
• This load is part of Barnes’ VOR-TX ammunition line, built around Barnes’ own bullet technology rather than a third-party projectile.
• Cases are brass, standard for reloading and reliable ignition.
• It ships 20 rounds to a box, the standard count for this loading.
• Cost works out to about $2.26 per round, in line with premium lead-free 6mm ARC ammunition.
