Why choose this pellet

The hollow-point configuration is intended to expand on impact while retaining the consistency required for useful grouping. Choose it when that design suits the target and your airgun groups it reliably.

Compatibility and responsible use

• Use only in an airgun marked for 4.5 mm (.177).
• Check the airgun and magazine manual before use; calibre alone does not confirm rotary-magazine fit.
• Test grouping under the same safe conditions because individual barrels can prefer different suitable pellets.
