Javelin Gen 2 5.5 mm (.217) 21 grain airgun slugs are very well-balanced because of their uniformity and consistent density, which is possible by having been swaged instead of forged. This second generation Javelin slugs underwent some changes to improve performances:
• Hollow point shape and depth have been redesigned to provide better expansion and weight distribution
• Meplat has been rounded-off for improved aerodynamics
