The Norma Golden Target .300 Norma Magnum 220gr HPBT (Model 20177712) is precision-engineered match ammunition designed for extreme long range (ELR) and target disciplines. Loaded with a 220-grain (14.3 g) Hollow Point Boat Tail projectile, this factory cartridge produces a muzzle velocity of 910 m/s (2,986 fps) and 5,924 Joules of muzzle energy from a 660 mm (26 in) test barrel. Featuring a 0.575 G1 ballistic coefficient, it maintains high supersonic stability and downrange energy retention, delivering 2,619 Joules at 600 metres for flat trajectories and minimal wind drift.

Key Features

• Aerodynamic HPBT Projectile: Streamlined 220-grain hollow point boat tail profile provides a 0.575 G1 ballistic coefficient for reduced aerodynamic drag.
• Extreme Downrange Performance: Achieves a muzzle velocity of 910 m/s, retaining 800 m/s at 200 metres and 605 m/s at 600 metres.
• High Energy Delivery: Generates 5,924 Joules of muzzle energy, sustaining over 4,000 Joules past 300 metres and 2,619 Joules at 600 metres.
• Match-Grade Tolerances: Built with premium match brass and consistent powder charges specifically for sport shooting and benchrest precision.
• Convenient Packaging: Supplied in standard 20-round factory boxes.

Who is the Norma Golden Target 300 Norma Mag 220gr 20 Pack for?

• Extreme Long Range (ELR) precision rifle competitors — requires a 0.575 G1 ballistic coefficient and a muzzle velocity of 910 m/s to minimise aerodynamic drag and maintain supersonic stability beyond 1,000 metres using .300 Norma Magnum match ammunition.
• Long-range benchrest sport shooters — utilizes the high kinetic energy retention of 2,619 Joules at 600 metres and a heavy 220-grain (14.3 g) projectile to ensure minimal wind drift during precision target matches.

Less suitable for: Medium-to-large game hunting due to the non-expanding match HPBT bullet design, which lacks controlled expansion; hunters should select dedicated hunting cartridges loaded with bonded polymer-tipped or expanding soft point projectiles. It is also unsuited for lightweight sporter platforms or standard chambers such as .308 Win, .300 Win Mag, or .300 PRC due to heavy recoil and dedicated chamber dimensions.
