Slug HP Features The H&N Slug HP is a pellet which 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 favorable ballistic coefficient (BC) ensures a flat trajectory and excellent energy retention. To accommodate different barrel profiles and power levels we offer options in diameter (.217 cal. / .218 cal.) and weight. The muzzle energy of the rifle should be at least 25 joules but for best results we recommend 40 to 60 joules. All pellets get visually inspected hand packed and secured for transport with foam pads. Slug HP Specifications Calibre: .22 Cal Weight: 23 Gr Min. Muzzle Energy: 18.5 Ft.lbs Max. Distance: 100 M BC: 0.094 Content Of Tin: 200 Pcs.
