Precision .338 Airgun Big Bore Bullets - Custom Weight, Metal Tip, Flat Base, ULD
Why Alco .338 Caliber Airgun Bullets
Alco is a small custom shop that makes handmade .338 caliber air big bore bullets for those that have this caliber of an air rifle. 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 pellets 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.
Alco Ultra Low Drag Bullets Performance Attributes
Alco takes pride in providing advanced aerodynamic .338 bullets which are designed to minimize air resistance in flight. These airgun bullets are built with the same precision as our centerfire .338 Ultra-low drag projectiles with a CNC metal tip to enhance accuracy. This allows Alco custom bullets to travel further, faster and with more precision than with a typical bullet. Key ULD features include:
- Streamlined Profile: A longer ULD bullet will minimize drag.
- High Ballistic Coefficient (BC): The high BC will offer aerodynamic efficiency and better performance with longer range shooting.
- Custom Swaged for consistency: Alco uses pure soft lead for maximum expansion that is swaged to provide a precise projectile with consistent diameter, weight and length.
- Reduced Drag – The custom big bore slugs are engineered to have less loss of velocity for increased range and accuracy.
- Pinpoint Accuracy: Efficient aerodynamics with less wind resistance increase accuracy over long distances
Additional Benefits in a .338 caliber Airgun Bullet
- Significant Energy and Stopping Power: The primary advantage of a .338 airgun bullet is its ability to deliver a substantial amount of energy to the target. Being a heavy and large-diameter projectile, it transfers more kinetic energy upon impact compared to smaller airgun calibers. This makes it highly effective for:
- Hunting Larger Game: For ethical hunting of medium to large game where legal (e.g., hogs, deer, coyotes, and even some bigger animals in regions where airgun hunting is permitted), the .338 offers the necessary power for clean and humane kills.
- Increased Knockdown Power: The larger mass helps to incapacitate targets more effectively, reducing the chance of an animal running off after being hit.
- Improved Long-Range Target Performance: A heavier .338 bullet tends to retain its energy and resist wind drift better than lighter, smaller-caliber airgun pellets at extended ranges. This can lead to:
- Flatter Trajectory: Over the practical ranges of powerful airguns, a heavier slug can maintain a more stable and predictable trajectory.
- Better Wind Resistance: The increased mass helps the bullet cut through wind more effectively, leading to less deviation and better accuracy at distance.
- Deeper Penetration and Larger Wound Channels: Due to its weight and diameter, a .338 airgun slug is capable of deeper penetration and creating a larger wound channel, which is crucial for hunting effectiveness.
Alco Terminal Ballistic Benefits – Those who use .338 hunting bullets will appreciate Alco’s excellent air rifle bullets designed for both extreme accuracy and maximum terminal ballistics. The Alco machined tips which enhance the pinpoint precision and range come off upon impact. On impact the tip separates from the lead causing devastating terminal ballistics when hunting game. The bullet basically becomes a hollow point which opens up and dumps all its energy into the cavity allowing for significant expansion to take down game humanely. The cores are composed of a swaged soft 100% lead which also helps with expansion.
Perfect Machined CNC Tips – Alco .338 bullet tips are manufactured on a precision machine using the highest quality metal for the best results for extreme long-range shooters. Engineered for solid pinpoint accuracy in competitive applications, the design allows you to create tight groups at all ranges. The tips give you a superior meplat of 0.002 which provides extreme aerodynamics and trajectory.
Handcrafted Excellence – Each Alco custom bullet is crafted and inspected by bullet smiths at every stage of the build for high-quality control. ALCO offers the best precision custom airgun bullets that are manufactured in Missouri and only use components made in the USA.
