S&B 762X39 124GR FMJ 20/600

Description

Sellier & Bellot’s 7.62×39mm Full Metal Jacket load is a straightforward choice for high-volume range work and general training with AKM-pattern rifles, SKSs, and AR-platform firearms chambered for the cartridge. The FMJ projectile is non-expanding by design, which keeps it appropriate for paper and steel without the cost premium of defensive or hunting loads.

The 124-grain bullet seats over a brass case and a boxer primer, a combination that matters to anyone who reloads: the case can be resized and reloaded multiple times, and the single spent primer punches out cleanly. The bullet jacket is CuZn 10 — a copper-zinc alloy — rather than a bimetal construction, which means it is non-magnetic and leaves no ferrous residue on barrel surfaces. Sectional density of 0.183 lb/in² gives the bullet reasonable resistance to deceleration for a round in this power class, and the G1 ballistic coefficient of 0.286 reflects realistic performance through the transonic transition rather than a figure measured in ideal conditions only.

Muzzle velocity is rated at 2,421 fps from a 20.5-inch test barrel, so expect modestly lower readings from the shorter barrels common on AK-pattern rifles. Energy at the muzzle runs just over 1,600 ft-lbs and drops to roughly 700 ft-lbs at 300 yards — adequate for practice drills at extended range. Primers are non-corrosive, so standard cleaning intervals apply. The 600-round case packs 30 boxes of 20, making it practical for sustained training sessions without constant resupply.
