Who This Is For
This load is purpose-built for deer, elk, and medium-to-large game hunters who shoot a 7mm-08 and want maximum downrange performance without handloading. Whether you're hunting high-altitude mule deer in early-season heat or late-season whitetails in freezing temps, the Superformance CX delivers consistent velocity, reliable expansion, and devastating terminal energy — shot after shot, right out of the box.

Frequently Asked Questions
What makes the CX bullet different from traditional cup-and-core hunting bullets?
The Hornady CX (Copper Alloy eXpanding) bullet is a monolithic-style projectile machined from a copper alloy rather than a traditional lead-core construction. This design delivers controlled, uniform expansion across a wide range of impact velocities, retains 95% or more of its original weight, and penetrates deeply even through heavy bone — making it exceptionally effective on medium and large game. It also leaves less fouling in the bore compared to many other mono-metal bullets.
Will this ammunition work in any standard 7mm-08 Remington rifle?
Yes. Hornady Superformance 7mm-08 139 GR CX is loaded to SAAMI specifications and is compatible with any standard 7mm-08 Remington chambered rifle. Despite the significantly higher velocity, chamber pressure remains within safe SAAMI limits, so there is no added stress on your action, bolt, or brass. Always consult your firearm's manual if you have questions about specific compatibility.
How does temperature affect the performance of Superformance ammunition?
One of the standout advantages of Hornady Superformance propellants is their low temperature sensitivity. Unlike some powders that can lose significant velocity in cold weather or spike pressure in extreme heat, Superformance propellants are formulated to maintain consistent velocities across a broad temperature range. This makes them a reliable choice for hunting in both frigid winter conditions and warm early-season environments.
