JSB Exact Heavy .177 Pellets
The JSB Exact Heavy is a domed lead airgun pellet designed for shooters who need extra performance at range from higher-powered .177 air rifles. At 10.34 grains — heavier than the standard Exact — it retains energy more effectively over distance and resists wind drift better than lighter alternatives, making it a strong choice for field target, longer-distance outdoor shooting and small-game hunting where downrange energy retention and stability matter. JSB’s signature domed head promotes consistent flight and reliable expansion on impact. Every pellet in the tin passes JSB’s thorough hand-pick quality-control process, meaning loose or misshapen pellets are removed before packing; the result is tight, consistent grouping straight from the tin. The 4.52mm head diameter suits the bore tolerance of most standard .177 air rifles.

Julia Ferguson –
Used these pellets in a field target setup and noticed much better grouping at 30 meters compared to standard pellets. The flight is stable and the impact is consistent. Good for longer-range shooting.
Charles Rampling –
Felt a noticeable difference in energy retention at distance. The pellets stay on course even in light crosswinds. Slightly heavier than standard, but worth it for outdoor use.
David Lee –
Excellent quality control. Every pellet feels uniform and the grouping is tight. Perfect for small-game hunting where accuracy matters.
Tracey Thomson –
Good performance in a high-powered air rifle. Retains energy better than lighter pellets, especially at 25 meters and beyond. Slight delay in initial velocity, but overall reliable.
