Winchester Ammo Bullet Supreme Bc 6.5Mm 140Gr 100/10

The Winchester Ammo Bullet Supreme BC 6.5mm 140-grain bullets are designed for reloaders who demand precision and consistency in their rifle ammunition. Loaded with a 140-grain polymer-tip projectile in the popular 6.5mm (0.264") diameter, these bullets combine a boattail design with a heat-resistant tip to achieve a respectable ballistic coefficient that supports long-range shooting. Each box contains 100 bullets—enough for serious practice or competition prep.

Winchester engineered these projectiles with controlled expansion in mind, thanks to a thick-walled jacket that balances reliable bullet performance across a range of velocities. The boattail profile and extended nose geometry work together to stabilize flight downrange, making them a sensible choice for hunters and precision shooters working loads for 6.5mm Creedmoor, 6.5×55, or similar cartridges. The polymer tip helps protect the bullet in the magazine and in flight, contributing to the overall G1 ballistic coefficient of 0.617 (or 0.304 G7).

These are uncoated, lead-core bullets with no cannelure, so you'll have the freedom to seat them to your preferred depth and crimp style. Winchester's quality control on their bullet-loading equipment means you're getting consistency from round to round—important when you're chasing tight groups or validating a new load development. If you're reloading 6.5mm ammo for distance shooting or general hunting, the 140-grain Supreme BC is worth testing in your rifle.

Frequently Asked Questions

What 6.5mm rifle cartridges can I load these bullets into?

The 6.5mm 140-grain Winchester Supreme BC is a standard projectile diameter (0.264") and weight that works in popular 6.5mm cartridges such as 6.5 Creedmoor, 6.5×55 Swedish Mauser, 6.5mm Remington Magnum, and other rifle rounds chambered in 6.5mm. Always consult your reloading manual for the specific cartridge you're loading and follow all published load data.

Are these bullets suitable for long-range hunting?

The boattail profile, extended nose design, and ballistic coefficients (0.617 G1 / 0.304 G7) are characteristic of bullets engineered for distance, and the thick-walled jacket is intended to support controlled expansion. However, actual performance depends on your rifle, velocity, and target distance. Test your loads in your firearm before relying on them in the field.

Do these bullets have a cannelure, and can I choose my seating depth?

No, these Winchester Supreme BC bullets have no cannelure, which gives you flexibility in seating depth and allows you to seat them to your preferred length without the constraint of a groove designed for crimping. This is useful for precision handloading and optimizing your load for your specific rifle.

What's included in the box?

Each box contains 100 uncoated, lead-core 140-grain 6.5mm bullets ready for reloading. You are responsible for providing the cases, primers, powder, and dies needed to complete your ammunition.
