- Purpose-designed .30 cal hunting pellet for PCP air rifles — 7.62mm, 44.75 grains
- Two-part construction: lead hollow-point body with red polymer tip for controlled expansion on impact
- Tip drives into hollow point on impact, increasing diameter and maximising energy transfer
- 13mm pellet length — longer than standard diabolo pellets; must be single-loaded into the chamber, not magazine-fed
- Patented design developed in partnership with JSB's US partners
- Pack of 100 pellets
The JSB Predator Polymag is a purpose-built hunting pellet for big-bore PCP air rifles, available here in .30 calibre (7.62mm) at 44.75 grains in a pack of 100. Developed in partnership with JSB's US partners, who hold a patent on this two-part construction, the pellet combines a lead hollow-point body with a red polymer tip seated in the nose. On impact the tip is driven back into the hollow point, forcing rapid expansion and transferring energy efficiently into the target — ideal for pest control and small-game hunting at range. At 13mm in length and 44.75 grains, these are heavy-for-calibre pellets that are longer than standard diabolo designs; they must be single-loaded directly into the chamber and will not seat correctly in a PCP rotary magazine. JSB's manufacturing tolerances are tight, with each pellet inspected to ensure dimensional consistency across the tin. The Polymag is a sound choice for hunters who need reliable terminal performance from a .30-calibre airgun.
