37 in stock

When only the tightest fit will do, the JSB Exact Jumbo 5.52mm provides the ultimate barrel-to-pellet seal. This "over-caliber" 5.52mm head is the preferred choice for many shooters whose rifles have slightly larger bores or prefer a more snug fit to improve consistency. Available in a convenient 250-pack, these .22 pellets deliver incredible energy transfer and stability at long distances. If you’ve struggled with grouping, switching to the 5.52mm Exact Jumbo is often the "magic fix" for achieving elite-level accuracy. - George

WHAT'S IN THE BOX
  • JSB 546247-250 Exact Jumbo .22 5.52mm Pellets 250pk
FREQUENTLY ASKED QUESTION(S)
  • Why buy a 250-pack of 5.52mm pellets? The 250-count tin is perfect for testing. Since the 5.52mm is the largest standard head size, this pack allows you to see if your rifle prefers a very tight fit without committing to a full 500-count tin.

  • Will 5.52mm pellets damage my air rifle barrel? No. Because JSB pellets are made of soft lead, the 5.52mm head will safely compress to fit your barrel, providing maximum grip and spin without causing wear.

  • Are these pellets suitable for FX or Daystate rifles? Many high-end rifles with "Smooth Twist" or "Liner" barrels perform exceptionally well with the 5.52mm head size, as it ensures positive engagement with the rifling.

  • What is the difference between JSB Exact and JSB Straton? The Exact is domed for maximum long-range stability, whereas the Straton is pointed. For most shooters, the Exact Jumbo 5.52mm offers superior accuracy at varied distances.

  • Does head size matter for pellet BC (Ballistic Coefficient)? Yes. A proper fit (like 5.52mm in a larger bore) ensures the pellet doesn't "wobble" in flight, maintaining a higher BC and a more predictable flight path.
