H&N Slug HP Heavy .22 / 5.51mm 36gr
Designed for long-range hunting and target shooting, the H&N Slug HP Heavy is a high-power .22 calibre airgun slug with a head size of .217″ (5.51 mm) and a weight of 36 grains. It offers greater downrange energy retention and a flatter trajectory compared to lighter projectiles.
Features a large-meplat hollow point with a star-shaped cavity machined into soft lead, engineered to expand reliably on impact for a clean, humane kill on small to medium game.
Developed in collaboration with Air Hunter Gerhard, a recognised authority in airgun performance, these slugs are suited to the faster rifling twist rates of modern regulated PCPs.

FAQ
What makes the H&N Slug HP Heavy different from standard airgun slugs?
The H&N Slug HP Heavy features a large-meplat hollow point with a star-shaped cavity in soft lead, designed to expand reliably on impact for better penetration and a clean kill. This design provides superior performance compared to conventional wadcutter or dome pellets, especially at longer ranges.
Is this slug suitable for use in all PCP air rifles?
It is best suited for modern regulated PCPs with faster rifling twist rates. Compatibility may vary depending on the specific rifle’s barrel twist and velocity characteristics. Please consult your rifle’s manual for optimal performance.
How does the slug perform in terms of energy retention over distance?
The 36-grain weight and optimized design deliver greater downrange energy retention and a flatter trajectory than lighter projectiles, making it effective for long-range shooting.

Joseph Sutherland –
Used this slug in my PCP rifle for target practice at 50 meters. The expansion on impact was consistent and the shot stayed on target. Much better than the standard wadcutter slugs I’ve tried before. Good for long-range accuracy.
Wanda Peake –
Felt a noticeable difference in trajectory compared to lighter slugs. The expansion was reliable and the rifle felt more stable at longer distances. Slightly heavier than expected, but worth it for hunting applications.
Lauren Gill –
Tested it on small game at 40 meters. The slug expanded properly and delivered a clean hit. The star-shaped cavity design seems to work well with my rifle’s twist rate. Highly recommended for serious target and hunting use.
