JSB Exact .177 | 500 pcs | 8.44 gr

The Benchmark of Consistency and Precision.

The JSB Match Diabolo Exact in .177 caliber is widely regarded as one of the most accurate and consistent pellets ever produced — a true benchmark for serious airgunners across disciplines. At 8.44 grains with a 4.53mm head diameter, this domed pellet is perfectly balanced for stability and accuracy across a wide range of air rifles, making it a trusted choice for field target competition, small game hunting, and extended range practice alike.

Overview

JSB's reputation was built on pellets like this one. The Exact's 4.53mm head diameter provides a consistent, snug bore seal that translates directly to uniform flight and repeatable accuracy. The 8.44gr domed profile strikes an ideal balance between velocity and stability — not so light that it loses energy quickly, not so heavy that it sacrifices speed. With 500 pellets per tin held to JSB's famously tight tolerances, this is the pellet serious shooters come back to tin after tin.
