The Sellier & Bellot 6.5×55 SE FMJBT 140 GRS ammunition delivers target-grade performance engineered for military surplus service rifles and modern bolt-action platforms. Loading a 140-grain (9.10-gram) Full Metal Jacket Boat Tail projectile (#2905), this factory cartridge produces a muzzle velocity of 787 m/s (2,582 fps) and 2,818 Joules of muzzle energy from a standard 600 mm test barrel. With a high G1 ballistic coefficient of 0.491 and a sectional density of 0.289 lb/in², the boat tail design resists wind drift and maintains stable supersonic flight past 600 metres. Each round features a non-corrosive Boxer-primed, reloadable brass case loaded within standard C.I.P. pressure limits to ensure safe, consistent feeding in vintage actions such as the Swedish M96 and M38 Mausers.

Key Features

• Aerodynamic FMJBT Projectile: Features a 140 gr bullet with a CuZn 10 alloy jacket and lead core, achieving a G1 ballistic coefficient of 0.491 (G7 of 0.247) to ensure flat trajectories and minimal wind deflection during long-range target shooting.
• Factory Ballistics: Generates a muzzle velocity of 787 m/s and 2,818 Joules of muzzle energy from a 600 mm barrel, with factory data zeroed for a Most Recommended Distance (MRD) of 163 metres.
• Bore-Friendly Metallurgy: The CuZn 10 metallic jacket prevents bore leading during sustained firing strings, preserving barrel life across extended range sessions.
• Reloadable Brass Cases: Assembled with factory-drawn Boxer-primed brass cases and non-corrosive nitrocellulose propellants suited for ambient operating temperatures from -20°C to +50°C.
• Extended-Session Packaging: Supplied in convenient 50-round packs designed for high-volume practice, load zeroing, and multi-stage vintage service rifle matches.

Who is the S&B Sellier & Bellot 6.5x55 Se 140 Grain Fmj Ammo 50 Rd for?

• Vintage Military Rifle Competitors — Delivers standard C.I.P. operating pressures safe for Carl Gustaf M96 and M38 service rifles while launching a traditional 140-grain projectile at 787 m/s, matching standard military sighting ladders in this 6.5x55mm rifle ammunition.
• High-Volume Target Shooters — Provides an economical 50 rounds packaging format that delivers a 0.491 G1 ballistic coefficient to maintain supersonic flight and flat trajectory past 600 metres during extended range sessions.

Less suitable for: Ethical medium-to-large game hunting due to the non-expanding full metal jacket projectile that produces narrow wound channels without mushrooming; an expanding soft point or monolithic hunting projectile in 6.5×55 SE is required for taking game. It is also strictly restricted to firearms chambered for 6.5×55 SE / Swedish Mauser and is incompatible with other 6.5mm chambers such as 6.5 Creedmoor or 6.5 PRC.
