The H&N Slug HP 217 30GR Pellet 5.51mm/.22Cal – 200PCS is a pellet that differs significantly from the usual pellets due to its bullet shape. It‘s designed for powerful rifles which can shoot such projectiles precisely at targets at 50, 100, or even 200 meters distance. An extremely favourable ballistic coefficient (BC) ensures a flat trajectory and excellent energy retention. The muzzle energy of the rifle should be at least 25 joules, but for best results, we recommend 40 to 60 joules.
