Hornady Monoflex .308 caliber 140-grain bullets bring lever-gun versatility to your reloading bench. Built on a copper-alloy construction that combines the best traits of two proven Hornady designs, these bullets deliver consistent expansion and deep penetration across the velocity ranges typical of lever-action rifles—from mid-range work to longer shots where lever guns still have game-taking power. If you're loading ammunition for a .308 lever gun and want a bullet engineered specifically for that platform, Monoflex rounds fill a real gap in the market.
The copper-alloy core (not pure copper) is the foundation here. It's harder and tougher than solid copper, resists fouling, and won't drive up pressure like softer solid-copper bullets can. On impact, Hornady's patented Flex Tip design initiates expansion reliably, even at the moderate velocities lever guns produce downrange. Weight retention runs high—the bullet holds about 95% of its original mass after impact—so you get the penetration and shock transfer hunters expect without core-jacket separation.
Each box contains 50 bullets, sized and ready for your .308 dies and press. Whether you're crafting hunting ammo for whitetail, elk, or other medium to large game, or working up loads for the range to dial in your lever gun's performance, Monoflex bullets handle the job with a track record of accuracy and reliability that Hornady stands behind.

These bullets are engineered for lever-action .308 rifles, where their design excels at lower to mid-range velocities. While the facts don't specify incompatibility with other .308 platforms, consult your rifle manual and load data to ensure safe use in your specific firearm and confirm powder charges and primers appropriate for your gun.
Hornady's copper-alloy construction is harder and tougher than pure solid copper, and it won't foul your bore or push pressure higher the way solid-copper rounds sometimes do. The alloy gives you the benefits of a monolithic bullet without those drawbacks.
Monoflex bullets are designed as hunting rounds. Their weight retention, penetration, and expansion characteristics make them appropriate for medium to large game hunted with .308 lever guns, though game suitability depends on your specific hunting application and local regulations.
The product facts don't specify any unique reloading requirements, so standard .308 reloading dies and equipment should work. Always consult current load data and your press manufacturer's guidelines before beginning any reloading project.
