About JSB Exact Monster Diabolo, 400 pcs, 4.52 mm (.177)
JSB Exact Monster in 4.52 mm is one of the heaviest diabolo pellets in .177, weighing 0.870 g (13.43 grains). The pellet is developed for the most powerful air rifles, where a heavy projectile uses the energy better and flies more stably at long range.
The tin contains 400 pellets with a 4.52 mm head size. Because of the weight, Exact Monster is best suited to powerful PCP rifles – in low-powered rifles the velocity is too low for a flat trajectory.
A heavy pellet for powerful rifles
Exact Monster is JSB's answer to what a powerful .177 rifle can handle.
- 0.870 g / 13.43 grains: One of the heaviest diabolos in 4.5 mm – more weight means more energy on target and less wind drift.
- 4.52 mm head size: The head size suits most modern .177 barrels – feel free to try both 4.50 and 4.52 to find the best accuracy in your rifle.
- For powerful air rifles: Developed for high-power rifles, where lighter pellets become unstable at high velocity.
- JSB quality: JSB is known for consistent pellets with small weight variations, which gives better grouping.
- 400 pcs: Tin of 400 pellets.
Maintenance and safety
Store the pellets dry in the closed tin so they do not oxidise or deform, and handle them as little as possible – soft lead pellets are easily marked, which affects accuracy. Wash your hands after handling lead pellets, and only shoot at a safe pellet trap.
