Single-Feed Design

For best results, push the bullet against the lands when loading to ensure proper engagement with the rifling. Be sure to verify compatibility with your specific airgun platform before ordering.

Compatibility Note:
ORION slugs are engineered for single-feed airguns and are not intended for magazine use.

Customer Range Report:
We recently received a great range report from a customer in South Carolina using the new Benjamin Bulldog M357. With the magazine removed, the ORION 160-grain slug was loaded by hand into the chamber. The customer noted that inserting the slug at a slight angle made loading easy, and accuracy was excellent. He was very pleased with the performance and plans to order more with his next purchase.

Designed for Competition and Hunting

The ORION .357 Airgun Slug is a 160-grain big bore airgun projectile built around a long Ultra-Low Drag (ULD) profile designed to reduce aerodynamic resistance and maintain trajectory in varying wind conditions.

The 160-grain ORION strikes a balance between aerodynamic efficiency, retained energy, and practical field performance. Its carefully engineered design supports predictable flight characteristics and dependable performance across a wide range of shooting applications.

This is not a hunting slug adapted for matches — or a match slug pressed into field use. It is a purpose-built projectile designed to excel in both roles.

ALCO Terminal Ballistic Design

Serious hunters demand more than accuracy alone. ALCO ULD projectiles are engineered to combine aerodynamic efficiency with dependable terminal performance.

The precision-machined tip is designed to enhance ballistic efficiency in flight and separate upon impact, initiating expansion. The resulting cavity works in conjunction with the soft swaged lead slug construction to promote effective energy transfer and dependable field performance.

While terminal results vary based on impact velocity, shot placement, and target conditions, every ALCO ULD design is developed with two goals in mind: exceptional accuracy and ethical hunting performance.

Accurate shot placement remains the most important factor in ethical hunting, and the ORION was engineered to support the precision required when performance matters most.

Ballistic Performance

Shooters looking for a high-performance .357 Airgun Slug will appreciate the ORION's combination of aerodynamic design, stability, and retained downrange energy.

The combination of a long ULD profile, precision-machined steel tip, and carefully controlled manufacturing process helps support:

• Consistent flight characteristics

• Improved resistance to wind drift

• Enhanced velocity retention

• Dependable energy retention

• Repeatable downrange performance

These design elements work together to help shooters maintain confidence as distances increase and conditions become more challenging.

Precision Manufacturing for Repeatable Results

Each projectile is precision-swaged from 100% soft lead and fitted with a custom-machined steel tip built to ALCO specifications. This manufacturing process helps provide:

• Superior bore seal

• Uniform rifling engagement

• Consistent velocities

• Repeatable shot placement

The result is a projectile built for consistency from shot to shot and lot to lot. Every production run is carefully monitored to help ensure the performance serious shooters expect from ALCO products.

Small Shop. Big Standards.

ALCO Bullets is a family-owned precision shop located in Missouri. We don't mass-produce projectiles by the millions. Instead, we focus on controlled production runs that allow us to maintain the quality standards our customers expect.

Our goal is simple: build projectiles we trust in our own airguns and rifles. No gimmicks. No shortcuts. Just the accuracy, consistency, and performance serious shooters expect.

By combining advanced projectile designs with precision swaging and controlled manufacturing processes, we strive to help shooters get the most from their equipment. The result is dependable performance and the confidence serious competitors and hunters demand when it matters most.

Careful design, precision swaging, and attention to detail throughout the manufacturing process help ensure every projectile performs to its potential. Whether on the competition line or in the field, that consistency gives shooters confidence in their equipment and their shot.

Because accuracy starts long before a trigger is pulled, every production run receives careful attention throughout the manufacturing process before being packaged and shipped.

Every ORION .357 Airgun Slug is produced with the same commitment to quality, consistency, and craftsmanship that defines every ALCO product.

Packaging

Packaged in protective 50-count containers to help ensure your slugs arrive in the same condition they leave our shop.

American-Made. Family-Owned. Precision-Built.

We're a family-owned precision shop — not a mass-production factory. Every projectile we produce is crafted with care, experience, and performance in mind.
