Sierra 7mm/.284 Caliber 140 Grain Bullets - 100 Count Box

Sierra's 7mm/.284 caliber 140 grain bullets deliver the balance of accuracy and terminal performance that serious reloaders demand. Whether you're loading for a 7-08, 7mm Rem Mag, or another 7mm chamber, these .284-diameter projectiles are engineered for consistent expansion and long-range capability. The 140-grain weight and robust construction make them a dependable choice for hunting applications where you need reliable bullet performance downrange.

Built with a reinforced jacket designed to control expansion while maintaining structural integrity, these bullets combine proven Sierra engineering with a sleek profile and polymer tip. The result is a round that resists wind drift and delivers the velocity stability serious handloaders expect from quality reloading components. With a 100-count box, you get enough bullets for serious load development or a full season of hunting prep.

If you're chasing tighter groups at distance or developing a load for medium to large game, these bullets reward precision in your reloading process. They're particularly well-suited to shooters who understand that bullet selection is half the equation—the other half is your meticulous attention to charge weight, primer selection, and case preparation. Sierra's reputation for consistency means you can focus on what matters: making every shot count.

Frequently Asked Questions

What 7mm rifles will these bullets work in?

These .284-diameter, 140-grain bullets are compatible with most 7mm rifle chambers, including the 7-08 Remington, 7mm Remington Magnum, 7mm-08, and other standard 7mm bottleneck cartridges. Always verify that your specific rifle's twist rate and bore dimensions are suitable for a 140-grain projectile before loading.

Are these bullets good for long-range hunting?

Yes. The ballistic coefficient (.545 at higher velocities) and streamlined profile make these bullets well-suited to extended-range hunting applications where wind drift and bullet drop matter. The reinforced jacket is designed to perform at hunting distances while maintaining consistent expansion.

How many bullets are in a box?

Each box contains 100 Sierra 7mm/.284 caliber 140-grain bullets, providing a standard reloading quantity for load development, practice, or hunting season preparation.

What is the ballistic coefficient for these bullets?

Sierra lists the ballistic coefficient as .545 at 1635 fps and above, .520 between 1400 and 1635 fps, and .470 at 1400 fps and below. BC varies slightly across velocity ranges, which is normal for hunting-weight bullets.
