H&N Slug HP Heavy .249 .25 Calibre 46 Grain Airgun Slugs
The H&N Slug HP Heavy is a precision-cast lead slug designed for high-power PCP air rifles in .25 calibre (.249″ / 6.34mm). Weighing in at 46 grains, it sits at the heavier end of H&N’s .25 slug range, retaining energy downrange and making it a capable choice for longer-range hunting and target shooting sessions.
The defining feature is a large-meplat hollow point combined with soft-lead construction: on impact, the cavity initiates rapid, consistent expansion that maximises energy transfer and produces a quick, humane kill — a quality that matters in the field.
Developed and tested in close collaboration with Air Hunter Gerhard, a well-regarded specialist in airgun hunting and precision shooting, the slug ensures performance under real-world conditions.

Joanne Morrison –
Used this slug in a long-range target session and noticed consistent expansion and good penetration. The weight and design make it reliable for outdoor shooting. Works well with my PCP rifle.
Joshua Young –
Good performance in field tests. The hollow point expands reliably and hits hard. A bit heavier than standard slugs, but that’s what I wanted for longer range.
Donna Glover –
Tested it with a high-power PCP rifle. The slug retained energy well and expanded properly on impact. Very satisfied with the design and performance.
