Alco Bullets sets the standard in precision-swaged .338 big bore airgun slugs, delivering high ballistic coefficient (High BC) performance engineered for serious competitors and hunters who demand measurable results.

The .338 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 powerful .338 caliber PCP air rifles are not mass-produced, they’re typically found in the custom gunsmith or boutique market. The .338 caliber bullets are built on an ultra low drag (ULD) design and come with a flat base and work best in a single feed air rifle. They are excellent in target applications as well as a solid hunting round. Alco has been making .338 caliber big bore slugs for customers with these unique air rifles and decided to offer them on our website to increase availability in the marketplace. The Alco .338 caliber big bore bullets are a specialty custom run. We can build these in heavier weights to work with your gun needs. Just call and we can produce these for you. The .338 Winchester Magnum, Lapua Magnum and other similar rifles are a popular choice for this application.

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 .338 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.

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.
