Big Bore .510 Hollow Point Airgun Slug

Superior Engineering

The Alco Air Boss line of hand-swaged precision big bore 50 Caliber (.510) air gun pellets is engineered for targets and to hunt big game effectively. The big bore 50 caliber Hollow Point .510 airgun pellet is composed of a swaged soft 100% lead with a flat base designed to humanely take down game. The hollow points will "mushroom" or expand upon hitting a soft target, increasing the wound channel for good terminal ballistics and more effective knockdown power. The bullets were designed with Umerax USA to use in the Hammer and will fit in most .510 caliber magazine feed as well as single feed airguns.

Pinpoint Accuracy

ALCO Big Bore pellet slugs are developed for PCP Air rifles which come in .308, .357, .452, .457 and .510 calibers. Working in conjunction with prominent airgun manufacturers, we developed the most accurate airgun pellets in the marketplace. The high-performance Alco big bore ammo provides you an edge for shooting accuracy, distance and lethality when hunting. We incorporate the same ULD design principles to provide the best pellets to surpass your expectations.

Handcrafted Excellence and Quality Control

The .510 Caliber Airgun pellets are sized and hand-checked during production for quality at each stage of the build. The quality airgun slug provides lower friction and a good air seal for rifling engagement. The projectile is built on an ultra-low drag ogive design for further increased accuracy. The swaged diameter control and consistent weight, allow for far greater precision-provided the shooter matches the diameter to his gun and can experiment with weight.

Terminal Ballistic Advantage

Hunters will appreciate these excellent air rifle bullets designed for extreme accuracy and maximum terminal ballistics. The hollow point upon impact allows the lead pellet to open up allowing for significant expansion to take down game humanely as it dumps more energy into the target.  Alco uses pure soft lead for maximum expansion that is swaged to provide a precise projectile with consistent diameter, weight and length. Alco big bore ammo provides you an edge for accuracy and lethality when hunting.

Match the Bullet Diameter to Your Gun

Alco recommends you know your airgun’s bore diameter before ordering. Not all airgun calibers are the same. You want to order the exact caliber pellet your gun needs.
