The Sellier & Bellot .300 Winchester Magnum 200 Grain SBT ammunition (Model: V332632) is engineered for medium-to-long-range big game hunting. Loaded with the Sierra GameKing Spitzer Boat Tail projectile (#2165), this factory cartridge delivers high ballistic efficiency, flat downrange trajectories, and deep penetration on heavy game. Each round utilizes a Boxer-primed, reloadable brass case built to standard .300 Win Mag specifications with an overall cartridge length of 84.80 mm.

Key Features

• Aerodynamic Sierra GameKing Bullet: Features a 200 gr Spitzer Boat Tail design that minimizes aerodynamic drag to maintain downrange velocity and reduce wind drift.
• High Ballistic Coefficients: Boasts a G1 ballistic coefficient of 0.530 (G7 of 0.266) and a sectional density of 0.301 lb/in² for sustained energy retention.
• Heavy Terminal Energy: Produces a muzzle velocity of 835 m/s and 4,518 Joules of muzzle energy from a standard 600 mm test barrel, retaining 2,483 Joules at 400 metres.
• Reloadable Quality Components: Assembled with standard Boxer primers and reloadable brass cases weighing 33.3 g per finished cartridge.

Who is the S&B Sellier & Bellot 300 Win Mag 200 Grain Sbt Sierra Boat Tail Ammo 20 Rd for?

• Hunters targeting large Sambar or Red deer at extended ranges — relies on a high 0.530 G1 ballistic coefficient and a heavy 200-grain projectile in this .300 Win Mag hunting ammunition to retain 2,905 Joules of kinetic energy at 300 metres for deep penetration on large cervids.
• Shooters pursuing feral camels or scrub bulls — utilizes a massive 4,518 Joules of muzzle energy and a muzzle velocity of 835 m/s to deliver high knockdown power through heavy bone and thick muscle.

Less suitable for: Close-range shooting under 50 to 100 metres where high muzzle velocity can cause rapid soft-point fragmentation; bonded-core or monolithic copper hunting ammunition is better suited for dense scrub and close-quarters impacts. It is also less optimal for rifles with barrel lengths under 600 mm, which will not achieve the rated 835 m/s velocity figures.
