Minuteman Munitions 300 Blackout 220gr Factory New Subsonic 30/Box

Minuteman Munitions 300 Blackout 220gr Subsonic FMJ (Factory New)

• Caliber: 300 AAC Blackout
• Bullet: 220 grain Full Metal Jacket (brass case)
• Advertised velocity around 1,030 ft/s from an 9″ barrel
• Designed to remain subsonic in barrels up to 11″
• Packaging: sold in 30-round boxes
• Backed by a one-year factory warranty against material and workmanship defects

This is Minuteman’s standard factory-new subsonic 300BLK load — the typical use case is suppressed short-barrel ARs or pistols (7″–11″ barrels) where you want reliable subsonic cycling without exposed-lead fouling in the can. It’s a range/plinking load, not an expanding defensive projectile.
