• High ballistic coefficient (BC) for long-range stability
• Increased weight and flat base design for maximum retained energy and momentum downrange
• Precision-swaged 100% soft lead core
• Designed for competition and hunting applications
• Built to Compete. Proven to Hunt.
Designed for Competition and Hunting
The TETON .457 Airgun Slug was engineered from the start to perform in both competitive shooting and hunting applications.
Its long ULD profile and proprietary aluminum tip help maximize ballistic efficiency, reduce drag, and maintain stability at extended distances. The increased weight and flat base design help maximize retained energy and momentum downrange while providing exceptional field performance when terminal authority matters most.
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.
Many shooters assume they must choose between long-range precision and dependable terminal performance. The TETON was engineered to deliver both.
Shooters seeking maximum retained energy and long-range capability from a .457 Airgun Slug will appreciate the balance of stability, momentum, and terminal performance offered by the TETON design.
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 proprietary aluminum 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 construction to promote effective energy transfer and dependable field performance.
The combination of the proprietary aluminum tip, flat base design, and soft swaged lead construction was developed to provide exceptional terminal performance without sacrificing long-range accuracy. The result is a projectile capable of delivering both the precision and stopping power serious hunters expect when ethical shot placement matters most.
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.
Real-World Results
ALCO ULD slugs have earned a reputation for dependable terminal performance in the field. One customer used an ALCO .457 ULD slug to harvest "Igor," a 500-pound boar during a hunt at Ted Nugent's Sunrize Acres property, reporting complete penetration and an ethical harvest.
Results vary based on platform, shot placement, and conditions, but real-world experiences like these help demonstrate the performance serious hunters expect from ALCO projectiles.
Ballistic Performance
Shooters looking for a high-performance .457 Airgun Slug will appreciate the combination of aerodynamic efficiency, retained energy, and exceptional long-range stability offered by the TETON design.
The combination of a long ULD profile, proprietary aluminum tip, increased projectile weight, and carefully controlled manufacturing process helps support:
• Consistent flight characteristics
• Improved resistance to wind drift
• Enhanced velocity retention
• Maximum retained energy
• Exceptional momentum downrange
• Repeatable long-range 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 aluminum 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.
