Balistix .338″ 250gr RBT UltraHunt Bullets – 25 Pack

The Balistix .338 250gr RBT UltraHunt Bullets feature an expansion-focused design for bush hunting and hunting applications. Their larger meplat creates a wider opening, which helps promote bullet expansion and mushrooming at shorter hunting distances.

Unlike the Target and HunTac ranges, the UltraHunt features a larger meplat and a lower ballistic coefficient. Therefore, this design focuses on bullet expansion rather than maximum ballistic efficiency.

Each box contains 25 monolithic copper bullets. In addition, Balistix combines CNC manufacturing, a rebated boat tail, tangent ogive and low-friction bearing surface. The Hexagonal Boron Nitride (HBN) treatment also helps reduce fouling and supports consistent performance.

Designed for Bush Hunting

The Balistix UltraHunt range focuses on hunting at shorter distances. Its larger meplat creates a wider opening at the front of the bullet. As a result, the design aims to promote a wider mushroom on impact.

Furthermore, the 250-grain version offers a heavier bullet option in the .338″ caliber. Its design prioritizes expansion for suitable hunting applications.

Larger Meplat and Bullet Expansion

The meplat refers to the small, blunt tip at the front of a bullet. The UltraHunt features a larger meplat than the Target and HunTac designs.

This wider opening supports the bullet’s expansion-focused design. However, it also results in a lower ballistic coefficient than the Target and HunTac ranges. Therefore, consider the intended hunting conditions when selecting the appropriate bullet range.

Pure Copper Monolithic Construction

Balistix makes these UltraHunt bullets from more than 99.5% pure copper. As a result, they offer a lead-free alternative to traditional lead-core bullets.

Copper has a lower specific gravity than lead. Therefore, a copper bullet can weigh less than a lead-core bullet of similar length. This difference may allow higher velocities with a suitable load. However, actual results depend on the rifle, cartridge and load.

Always follow the manufacturer’s recommendations when selecting bullet weight for your rifle’s barrel twist rate.

Rebated Boat Tail Design

The rebated boat tail helps manage gas flow as the bullet exits the muzzle. In addition, its shape combines the ballistic benefits of a boat-tail profile with a design intended to support precision.

Balistix states that this design can improve precision and accuracy by up to 15% compared with a conventional boat tail. However, actual results vary with the rifle, load and shooting conditions.

Tangent Ogive Design

The UltraHunt bullet features a tangent ogive, which is less sensitive to bullet jump. Therefore, reloaders have more flexibility when adjusting seating depth during load development.

The ogive engages with the rifling lands rather than using a bore-rider design. Furthermore, reloaders can use an ogive comparator tool to measure bullet position and fine-tune seating depth.

Low-Friction Bearing Surface

Balistix designs the bearing surface within SAAMI tolerances. It also uses a low-friction drive-band design to help reduce copper fouling and support lower-pressure characteristics.

As a result, this design aims to promote consistent performance. Always use suitable published load data and follow safe reloading practices.

Hexagonal Boron Nitride (HBN) Treatment

Hexagonal Boron Nitride, or HBN, acts as a solid lubricant and handles high temperatures well. Balistix applies this treatment to help improve the performance of its monolithic copper bullets.

The HBN treatment aims to:

• Reduce fouling compared with untreated monolithic bullets.
• Help reduce pressure compared with untreated bullets under suitable conditions.
• Reduce extreme velocity spread.
• Support consistent accuracy between cold-bore and follow-up shots.
• Help reduce elevation dispersion.

Therefore, HBN treatment may help support more consistent results. However, actual performance depends on the rifle, load and shooting conditions.
