Product description

Light round-nose airgun pellet for higher velocity and good precision in 10 J air rifles

JSB Exact Jumbo RS is a light pellet in 5.5 mm caliber, designed to give higher muzzle velocity and good accuracy, especially in air rifles with power around 10 joules. RS stands for Rapid Speed, which means this is one of the lighter variants in the Exact series.

The lower weight allows the pellet to accelerate faster in the barrel, which often results in a flatter trajectory, making it easier to shoot at short to medium ranges. In many non-license air rifles, this type of pellet can noticeably improve shot groupings compared to heavier alternatives.

The Exact series is JSB's most widely used series and a well-established choice among both hobbyists and competitive shooters. The classic round-nose shape, together with even weight distribution, provides stable flight and good precision at distances well beyond 10 meters.

How to choose the right pellet

The choice of pellet has a major impact on the accuracy of an air rifle. Different barrels can perform differently with various weights and dimensions, and it's often only when you find the right combination that the firearm performs at its best.

This model is intended for caliber 5.5 mm / .22, but has a head diameter of 5.52 mm. This is standard for precision pellets in this caliber. The measurement refers to the pellet’s head, not that it belongs to another caliber. In practice, 5.52 mm often works very well in 5.5 mm air rifles, and in many barrels even better than 5.50 mm and 5.51 mm. Therefore, 5.52 mm is also one of the most popular sizes in 5.5 mm caliber.
