The Hornady CX 25 Cal .257 90 gr Boat-Tail Hunting Bullets are a premium reloading choice for hunters and precision shooters looking for non-traditional ammunition in regulated hunting areas. Built from a monolithic copper alloy instead of lead, the CX platform delivers the penetration and weight retention you need for medium to large game while meeting California and other regional ammunition restrictions. If you reload for .257-caliber rifles and want a bullet that combines modern aerodynamics with proven terminal performance, these Hornady CX rounds are engineered to deliver accuracy and consistency from first shot to last.
What sets the CX apart is its one-piece copper construction—there's no core-jacket separation, just solid penetration and a 95% weight retention rate that speaks to the durability of monolithic bullet design. The proprietary Heat Shield Tip is molded from heat-resistant polymer that holds its shape through the extreme aerodynamic stress of long-range flight, maintaining a consistent ballistic coefficient and ensuring a perfectly uniform meplat (tip) shot to shot. That consistency matters when you're handloading: every round chambers and flies the same as the one before it.
The grooved bullet geometry is optimized for aerodynamic efficiency while keeping bearing surface low enough to reduce copper fouling in your barrel. At 90 grains in .257 caliber with a boat-tail profile, this bullet is sized for rifles chambered in .257 weatherby magnum and similar cartridges. Whether you're hunting in California, the West, or anywhere non-lead ammunition is preferred or mandated, the Hornady CX line offers the performance and terminal reliability hunters have come to expect from Hornady's engineering.

Frequently Asked Questions
What rifles are Hornady CX 25 Cal .257 90 gr bullets compatible with?
These bullets are sized for .257-caliber rifles, including .257 Weatherby Magnum and other cartridges that use the .257 bullet diameter. Always verify your specific rifle's chambering and load data before reloading.
Are Hornady CX bullets California-legal?
Yes. The CX line is fully California-compliant and meets non-traditional (non-lead) ammunition requirements in California and other regions with similar regulations.
What does 95% weight retention mean?
Weight retention refers to how much of the bullet's original weight remains after impact and penetration. The 95% retention rate of the CX bullet means minimal fragmentation or loss of material, resulting in deeper, more consistent penetration in game.
What's included in the part number 254104?
The part number denotes the specific load: Hornady CX in .257 caliber at 90 grains. Order quantities vary; check the product listing for how many bullets are included per box or bag.
