Atomic 6.5cm Subsonic 129gr Sp - 20rd 10bx/cs

The Atomic 6.5cm Subsonic 129gr SP ammunition delivers suppressed-fire capability for tactical operators, law enforcement precision marksmen, and military personnel requiring subsonic performance without the auditory signature of supersonic rounds. This 20-round-per-box configuration is engineered for use with sound suppressors, making it ideal for close-quarters operations, covert insertions, and training scenarios where noise discipline is mission-critical. Each carton contains 10 boxes, providing 200 rounds of consistent, field-proven ammunition for sustained training or operational deployment.

The 129-grain soft-point projectile is specifically designed to remain subsonic—traveling below the speed of sound (approximately 1,125 feet per second)—eliminating the supersonic crack that compromises stealth and reveals shooter position. Atomic Ammunition manufactures this round with precision quality control, ensuring consistent velocity and accuracy downrange. The soft-point construction provides controlled expansion on impact, making it suitable for both target work and defensive applications where barrier penetration and terminal performance matter equally.

This ammunition pairs seamlessly with bolt-action and semi-automatic rifles chambered in 6.5cm, particularly those equipped with quality sound suppressors. Professional end-users—from tactical operators and PSD teams to designated marksmen and ammunition testers—rely on Atomic's consistency for mission-critical accuracy and ballistic predictability. Storage is straightforward; keep rounds in a cool, dry environment, and inspect casings before use. The 1.01 lb package weight and compact box dimensions (3.1 x 1.65 x 6.2 inches) make field transport and inventory management practical for high-volume tactical training or deployment.
