ALCO .308 Airgun Slug 150-Grain ULD Steel Tip Flat Base

The ALCO .308 Airgun Slug 150-Grain ULD Steel Tip Flat Base is a proprietary, airgun-engineered design built for precision and decisive field performance. Its extended Ultra-Low Drag (ULD) profile and custom CNC-machined steel tip enhance ballistic efficiency and promote exceptional high-BC stability, making it well suited for both competition and hunting applications where consistent, repeatable performance at distance matters.

Unlike many traditional .308 airgun slugs, the ALCO 150-Grain ULD was developed around a true Ultra-Low Drag philosophy rather than conventional airgun slug geometry. Its extended profile and custom CNC-machined steel tip create a longer, more aerodynamically efficient projectile designed to maximize ballistic coefficient, stability, and downrange performance.

With a G1 BC of 0.810 and an overall length of 1.20 inches, the ALCO 150-Grain ULD represents the next step in long-range .30 caliber airgun performance. The additional weight and increased ballistic efficiency help the slug retain velocity, resist wind drift, and maintain energy at extended distances while preserving the accuracy and consistency serious shooters demand.

For hunting applications, shooters should consider their platform, setup, and effective range to ensure ethical, responsible shot placement.

ALCO .308 Airgun Slug Built for Maximum Long-Range Performance

The ALCO 150-Grain ULD Steel Tip Flat Base was developed for shooters seeking maximum downrange performance from modern .308 caliber PCP air rifles. The combination of increased weight, high ballistic coefficient, and advanced ULD design makes this slug particularly well suited for long-range target shooting, competition, and hunting applications where wind resistance, retained energy, and shot-to-shot consistency matter.

ALCO precision-swaged slugs are designed for modern big bore PCP air rifles. While some shooters refer to them as airgun bullets or pellets, these projectiles are engineered specifically for today's high-performance airgun platforms, delivering the accuracy, consistency, and terminal performance serious shooters demand.

The 150-Grain ULD is intended for shooters who want to maximize the capabilities of their .308 airgun at extended distances. Its efficient profile helps reduce wind drift, maintain velocity, and deliver consistent performance throughout a wide range of shooting conditions.

Compatibility and Loading

The ALCO .308 Airgun Slug was designed for single-feed big bore airguns and performs exceptionally well in platforms such as the AirForce Texan and other .30 caliber airguns that support longer ULD projectiles.

ALCO precision-swaged slugs are designed for modern big bore PCP air rifles. While some shooters refer to them as airgun bullets or pellets, these projectiles are engineered specifically for today's high-performance airgun platforms, delivering the accuracy, consistency, and terminal performance serious shooters demand.

For best results, gently push the slug forward until you feel engagement with the lands before firing. Proper rifling engagement helps maximize the accuracy potential of the ULD design.

Designed for Competition and Hunting

The ALCO .308 Airgun Slug 150-Grain ULD was engineered from the start to perform in both competitive shooting and hunting applications.

Its extended ULD profile and custom CNC-machined steel tip help maximize ballistic efficiency, reduce drag, and maintain stability at extended distances. The combination of aerodynamic efficiency, high BC performance, and increased retained energy supports exceptional long-range accuracy while delivering dependable field performance when it 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 ALCO 150-Grain ULD was engineered to deliver both.

ALCO Terminal Ballistic Design

Serious hunters will appreciate a projectile built for both accuracy and dependable terminal performance. The custom CNC-machined steel tip enhances ballistic efficiency in flight and is designed to separate upon impact, initiating expansion.

The resulting cavity works in conjunction with the soft swaged lead core to promote effective energy transfer and dependable field performance. This design allows the .308 ULD to maintain exceptional aerodynamic efficiency in flight while delivering the terminal performance hunters expect when ethical shot placement matters most.

For hunting applications, shooters should consider their platform, setup, and effective range to ensure ethical, responsible shot placement.

Ballistic Performance

Shooters looking for a high-performance .308 Airgun Slug will appreciate the combination of aerodynamic efficiency, retained energy, and exceptional long-range stability offered by the ULD design.

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

• Consistent flight characteristics

• Improved resistance to wind drift

• Enhanced velocity retention

• Excellent downrange energy retention

• 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 steel tip built to ALCO specifications. This manufacturing process helps provide:

• Superior bore seal

• Uniform rifling engagement

• Consistent velocities

• Repeatable shot placement

Every production lot is carefully monitored and accuracy tested to help ensure the performance serious shooters expect from ALCO products.
