ATOMIC‘s Subsonic ammunition in 7.62x39mm (brand part no. 00474) loads a 220-grain hollow point boat tail at 1,050 feet per second, nearly double the weight of a standard 123-grain 7.62×39 bullet, chosen specifically to hold subsonic velocity in this cartridge. ATOMIC engineers this as a Tactical Cycling Subsonic round, tuned to reliably cycle an AK-platform action even at the reduced pressure a subsonic load produces, rather than short-stroking like many subsonic loads do. At 1,050 fps, the heavy 220-grain bullet still generates 538 ft-lbs of muzzle energy, quiet enough to make a real difference through a suppressor. Made in the USA and loaded in reloadable brass, this rifle ammunition ships in a reusable plastic box built for repeat trips to the range.

Frequently Asked Questions

Why is 220gr so much heavier than standard 7.62×39 ammo? A heavier bullet is needed to hold subsonic velocity at the reduced pressure a subsonic load runs.

What does Tactical Cycling Subsonic mean? ATOMIC tunes this load to reliably cycle an AK-platform action even at subsonic pressure, where many subsonic loads short-stroke.

What is the muzzle velocity and energy? 1,050 fps and 538 ft-lbs of muzzle energy.
