The Norma VerminXtreme .22-250 Remington 55gr HP ammunition (MPN 20157852) is engineered for aggressive predator management and vermin eradication. Loaded with a 55-grain (3.6-gram) blunt-nosed hollow point projectile, this factory cartridge achieves a muzzle velocity of 3,576 fps (1,090 m/s) and a muzzle energy of 2,139 J (1,562 ft-lbs) from a 24-inch (610 mm) test barrel. Built with reloadable boxer-primed Swedish brass, the round utilizes an aggressive hollow point cavity designed to expand and fragment violently on impact, delivering maximum hydraulic shock and immediate energy transfer to thin-skinned game.

Key Features

• Rapid-Fragmenting Hollow Point: Features a blunt-nosed hollow point bullet engineered for violent expansion and rapid fragmentation upon impact, reducing ricochet risks.
• High-Velocity Ballistics: Delivers 3,576 fps at the muzzle, maintaining 859 m/s (1,328 J) at 100 metres and 663 m/s (791 J) at 200 metres.
• Optimised Trajectory: Configured for a most recommended distance (MRD) zero of 188 metres (210 yards) for short-to-medium-range pest control.
• Premium Reloadable Casing: Boxer-primed, high-grade brass manufactured in Sweden ensures consistent feeding across bolt-action and compatible sporting actions.

Who is the Norma VerminXtreme .22-250 Remington 55gr HP for?

• Rural property owners controlling feral foxes and wild dogs — requires lethal energy transfer delivered by this .22-250 Remington varmint ammunition, which produces 3,576 fps at the muzzle and retains a flat trajectory aligned with its 188 m recommended zero.
• Pest controllers targeting rabbits, hares, and feral cats — benefits from the rapid-fragmenting 55 grains hollow point design of this .22-250 Remington cartridge, which expands violently on impact with a 0.149 G1 ballistic coefficient to drop thin-skinned pests immediately without ricochet.

Less suitable for: Shooting past 300 m where velocity falls to 496 m/s and the 0.149 G1 ballistic coefficient introduces significant wind drift (where high-BC polymer-tipped or boat-tail varmint rounds are better suited), or for hunting medium-to-large game such as deer and large feral pigs where rapid fragmentation fails to penetrate (where controlled-expansion bonded hunting bullets are required).
