Alco .308 (30 Caliber) 150-Grain ULD Metal Tip/Flat Back Big Bore Airgun Slugs

Alco Bullets sets the standard in precision-swaged .308 big bore airgun slugs, delivering high ballistic coefficient (High BC) performance engineered for serious competitors and hunters who demand measurable results.

The .308 Alco Ultra-Low Drag (ULD) Metal-Tipped Airgun Bullet features a proprietary long-form metal tip developed in-house by Alco specifically for big bore airgun velocities. The result is enhanced ballistic efficiency, reduced drag, and superior long-range stability compared to conventional big bore slugs.  NOTE: The .308 bullet works well in the Airforce Texan and single feed others that are that in caliber.

ULD Design for Accuracy

Alco's extended ULD design with custom CNC metal tip increases ballistic coefficient and helps the slug retain velocity downrange. By minimizing drag and maintaining stability, the Lancer delivers:

• Tighter groups at extended distances
• Improved resistance to wind drift
• More consistent flight from muzzle to impact
• Reliable energy retention for terminal performance

Shooters will notice the difference when pushing distances where traditional hollow-point-only slugs begin to lose efficiency.

Built to Compete. Proven to Hunt.

The .308 big bore was engineered from the start to perform in both competitive target shooting and hunting applications.

Its precision weight consistency and high-BC stability support match-grade accuracy, while the mass and controlled impact characteristics provide dependable knockdown authority in the field.

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

ALCO Terminal Ballistic Design

Serious hunters will appreciate a bullet built for both accuracy and consistent terminal performance. The machined metal tip enhances precision and ballistic efficiency, then separates on impact to initiate expansion. This creates an open cavity while the jacket and soft lead core work together to maintain structure and deliver controlled energy transfer.

The swaged 100% lead core and hollow back design support reliable expansion, contributing to consistent performance in the field. Balanced for versatility across a wide range of setups.

Precision Manufacturing for Repeatable Results

Each projectile is precision-swaged from 100% soft lead and fitted with a custom-machined metal tip built to Alco specifications. This manufacturing process provides:

• Superior bore seal
• Uniform rifling engagement
• Consistent velocities
• Repeatable shot placement

Every production lot is extensively accuracy-tested before release to ensure dependable, “dead-on” performance — shot after shot.

Real Craftsmanship. Precision Without Compromise.

Alco Bullets are not mass-produced. They are handcrafted in small batches with meticulous attention to detail at every stage of production. Every slug is:

• Individually inspected
• Consistent weight, diameter, and concentricity
• Built with consistency as the priority

When every thousandth of an inch matters, this level of control translates directly into measurable accuracy — whether you're on the bench or in the field.

Handcrafted. Verified. Proven.

Why Alco Is Different

• Proprietary Ultra-Low Drag (ULD) metal tip design
• Developed specifically for big bore air gun
• High Ballistic Coefficient (High BC) performance
• Custom small-batch manufacturing
• Individually inspected projectiles
• 100% soft swaged lead construction
• Designed for single-feed big bore airguns

Single-Feed Tip:
When shooting single-feed airguns, gently push the bullet forward in the chamber until you feel resistance to properly engage the lands for optimal accuracy.
