Hornady CX 6mm .243 80 grain bullets deliver serious terminal performance for hunters who demand reliability across a range of game sizes. Built as a monolithic copper alloy projectile, the CX design won't shed jacket material mid-flight — it stays together through bone and muscle to maximize energy transfer where it counts. This 50-count box gives you a quality hunting round suitable for everything from medium to large game, with the added benefit of full California compatibility if you're hunting in restricted-ammunition states.
The engineering behind CX bullets focuses on what matters downrange: consistency and penetration depth. The Heat Shield Tip is engineered from heat-resistant polymer to hold its shape through the friction of flight, maintaining a uniform meplat (bullet tip) for shot-to-shot uniformity. That stable tip geometry translates to cleaner BC performance and tighter grouping — critical when you're setting up a shot on distant game. The groove design balances aerodynamics with reduced fouling, so your barrel stays cleaner and your accuracy stays sharp across multiple shots.
Whether you're handloading for a .243 Winchester or another 6mm platform, CX bullets bring the kind of terminal behavior that separates hunters who harvest cleanly from those who don't. One-piece construction means 95% weight retention — the bullet does the job you bought it to do without fragmenting prematurely. If you're reloading ammunition for hunting and want a monolithic option that performs reliably across varied terrain and game, CX projectiles are worth your attention.

Frequently Asked Questions
What game is the Hornady CX 80-grain .243 bullet suitable for?
CX bullets are appropriate for medium-size to large game hunting. The monolithic design and deep penetration characteristics make them effective across a range of applications where reliable terminal performance is essential.
Can I use CX bullets in California or other restricted ammunition areas?
Yes. Hornady CX bullets are fully California-compatible and meet nontraditional ammunition requirements in states and regions that restrict lead-core projectiles.
What does the Heat Shield Tip do?
The Heat Shield Tip is constructed from heat-resistant polymer to resist degradation from aerodynamic heating during flight. It also ensures a perfectly uniform meplat (tip) for consistent bullet-to-bullet and lot-to-lot accuracy and performance.
How much does a CX bullet weigh after impact?
CX bullets retain approximately 95% of their original weight, meaning minimal material is shed during terminal performance. This weight retention supports deep penetration and controlled expansion on game.
