The Barnes VOR-TX 300 Winchester Short Magnum 165 grain Tipped Triple-Shock X (TTSX) represents a purpose-built hunting load for hunters who require reliable terminal performance across variable shot angles and tissue densities. The 300 WSM cartridge pushes the 165-grain monolithic copper projectile to 3130 feet per second, generating 3590 foot-pounds of muzzle energy at the muzzle. This combination delivers flat trajectories and sufficient momentum for elk, mule deer, and other large-bodied game at ranges where many cup-and-core bullets lose expansion reliability. The lead-free construction meets regulations in California condor zones and other restricted areas, making it a field-legal option for hunters navigating patchwork ammunition restrictions across state and federal lands.
Performance at a Glance
The TTSX bullet relies on a machined all-copper body with a polymer tip that drives expansion initiation upon impact. Four pre-formed petals peel back from the nose, creating a frontal diameter roughly twice the original bore size while the solid copper shank retains 99% or more of its original weight. This weight retention translates to deeper penetration through heavy bone and muscle compared to fragmenting lead-core designs. The 0.442 G1 ballistic coefficient supports extended-range trajectories, and the boat-tail base reduces drag. Barnes loads these rounds with temperature-stable powder, flash-suppressed primers, and brass cases headstamped for the 300 Winchester Short Magnum.

The 165-grain TTSX sits in the middle of the bullet-weight spectrum for 300 WSM, balancing velocity with sectional density. Lighter 150-grain loads gain another 100 fps but shed wind-bucking ability; heavier 180-grain offerings improve penetration at the cost of flatter trajectories. Handloaders can resize the once-fired brass and reload with powders like Hodgdon H4350 or Alliant Reloder 17, adjusting charge weights to match bullet seating depth.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Follow the four rules of firearm safety at all times — treat every firearm as if it is loaded, never point the muzzle at anything you are not willing to destroy, keep your finger off the trigger until ready to fire, and be certain of your target and what lies beyond it.
- Verify current state and local laws before purchasing or possessing ammunition — some jurisdictions require background checks, permits, or impose waiting periods.
- This ammunition contains lead and other materials known to the State of California to cause cancer, birth defects, or reproductive harm under Proposition 65. Wash hands after handling and avoid ingestion of residue.
