Underwood Ammo .300 AAC Blackout 125-grain Ballistic Tip ammunition (part no. 418) loads a lightweight, supersonic bullet for AR-platform shooters who want a controlled-expansion hunting round rather than the heavier subsonic loads the caliber is often known for. Underwood Ammo tops this 125-grain bullet with a Ballistic Tip nose that initiates rapid, consistent expansion on impact while improving the bullet’s ballistic coefficient for a flatter trajectory than a flat-point bullet would deliver. It is built for hunters and shooters who want their .300 Blackout running fast and flat rather than slow and heavy. In rifle ammunition for AR-platform hunting, this is the supersonic side of the Blackout lineup.

Key Specifications

• The chambering is .300 AAC Blackout, an AR-15-compatible cartridge built to run supersonic or subsonic loads from the same magazine.
• The bullet weighs 125 grains, light enough to run at supersonic velocity for flatter trajectory and more energy on impact.
• The bullet uses a Ballistic Tip nose, initiating rapid, controlled expansion on impact.
• The polymer tip also improves the bullet’s ballistic coefficient, helping it retain velocity and fly flatter downrange.
• Each box holds 20 rounds, shipped 10 boxes to the case.
• Cost runs about $1.70 per round for a purpose-built supersonic hunting load.
• This load is built for AR-15 rifles and pistols chambered in .300 AAC Blackout.
• Running supersonic means this load produces a normal sonic crack rather than the quieter report of a subsonic .300 Blackout round.
• The polymer tip also improves the bullet’s aerodynamic profile compared to a flat-point or round-nose bullet of similar weight.

Frequently Asked Questions

Is this a supersonic or subsonic .300 Blackout load? At 125 grains, this is a supersonic load, built for flatter trajectory and rapid expansion rather than the reduced-noise performance of heavier subsonic Blackout ammunition.

What game is this load suited for? The Ballistic Tip’s controlled expansion makes it a solid choice for deer-sized game and hogs at typical .300 Blackout hunting distances.
