DoubleTap’s .300 AAC Blackout 220-grain Hollow Point Boat Tail load (brand part no. 300BK220MK) is built heavy-for-caliber, the kind of weight shooters reach for when running a .300 Blackout suppressed. The hollow point cavity opens on impact for controlled expansion, while the boat-tail base keeps the bullet’s ballistic coefficient higher than a flat-base design, holding velocity and accuracy further downrange. Double Tap Ammunition hand-loads its ammunition in small batches, giving handloaders and precision shooters a level of consistency mass-produced loads often miss. Heavy 220-grain bullets in .300 Blackout are the standard weight class for subsonic, suppressor-friendly shooting, where a quiet, still-lethal round matters more than outright velocity. In rifle ammunition built for AR pistols and short-barreled rifles, this load fills a specific and well-understood role.
Key Specifications

- The bullet weighs 220 grains, the heavy-for-caliber class typically loaded to subsonic velocities.
- The bullet type is hollow point boat tail, combining an expanding tip with an aerodynamic base.
- The hollow point cavity opens on impact, expanding for controlled energy transfer rather than passing straight through.
- The boat-tail base improves the ballistic coefficient, helping the bullet hold velocity and accuracy at extended range.
- The case material is brass, supporting reliable extraction and consistent chamber pressures.
- The cost per round runs about $2.06, in line with small-batch, precision-loaded ammunition.
- Each box holds 20 rounds, a practical amount for a range or practice session.
- A full case packs 50 boxes for 1,000 rounds total, useful for stocking up in bulk.
- The heavy bullet weight suits subsonic, suppressor-friendly shooting, common on short-barreled .300 Blackout builds.
Frequently Asked Questions
Is this a subsonic load? The 220-grain weight is the class commonly loaded to subsonic velocities in .300 Blackout, though shooters should verify velocity for their specific suppressor and barrel setup.
Does the hollow point expand? Yes, the hollow point cavity is designed to open on impact for controlled expansion rather than pass through like a full metal jacket bullet.
How many rounds are in a full case? A case holds 50 boxes of 20 rounds each, for 1,000 rounds total.
