The Barnes Steward Collection .243 Winchester 70-grain Sierra Tipped VarmintKing (TVK) Brass 20-round box is specialized centerfire rifle ammunition engineered specifically for long-range predator control, high-velocity varmint hunting, and property management. A primary operational limitation when targeting coyotes, foxes, and small game with dual-purpose .243 Win rifles is the use of heavy medium-game bullets that pass through light-bodied varmints without expanding, resulting in runner tracks across open pastures. Barnes resolves these terminal performance friction points by pairing precision factory loading standards with Sierra’s lightweight, aerodynamic 70-grain Tipped VarmintKing projectile, maximizing .243 case capacity to deliver laser-flat flight paths, tight crosswind resistance, and explosive terminal fragmentation.
The core technical advantage relies on the projectile's 70-grain Sierra Tipped VarmintKing (TVK) architecture. Featuring an aerodynamic polymer tip paired with a thin copper jacket and swaged lead core, the bullet yields an elevated ballistic coefficient for flat shooting over extended distances. Upon contact with target tissue, the polymer tip acts as an internal wedge, driving violently backward into the lead core to initiate immediate, explosive jacket fragmentation. This total energy transfer eliminates pass-throughs and anchors small predators instantly without energy loss or exit-wound tracking.
Purpose-built to maximize muzzle velocity while maintaining match-grade benchrest accuracy, this 70-grain loading provides exceptional trajectory control across short and long shooting lanes. Assembled in premium reloadable virgin brass cases paired with clean-burning propellants and non-corrosive Boxer primers, the cartridge guarantees uniform chamber pressures, low velocity standard deviations, and smooth cycling across bolt-action and semi-automatic .243 Winchester platforms.
Key Benefits
- Explosive Terminal Expansion: Thin copper jacket and polymer tip drive instant, complete fragmentation on small targets.
- Hyper-Velocity Trajectory: Lightweight 70-grain payload maximizes case capacity for ultra-flat trajectories and minimal holdover.
- Aerodynamic Polymer Tip: Protects bullet nose geometry during magazine feeding while stabilizing flight against harsh crosswinds.
- Premium Reloadable Brass: Precision-drawn factory brass cases and non-corrosive Boxer primers ensure smooth cycling and reliable ignition.
