What to know

Expanding .300 BLK comes in two flavors: supersonic (110—125gr) for maximum terminal effect, and subsonic (190gr+ Sub-X) for suppressed use. Barnes TAC-TX is the most popular supersonic expanding load. Hornady Sub-X is the only widely available subsonic that reliably expands. Premium pricing reflects the specialty nature of these loads.

Frequently asked questions

Which .300 Blackout hollow points are available for defense?
Hornady V-MAX 110gr and Barnes TAC-TX 110gr are supersonic expanding loads. Hornady Sub-X 190gr is engineered to expand at subsonic velocity, unlike conventional JHP bullets that may require higher impact velocity.
How is .300 Blackout JHP priced?
.300 Blackout hollow point and expanding loads come in supersonic and subsonic versions (such as Hornady Sub-X), and premium hunting loads cost the most. Current observed .300 Blackout prices are in the 30-day price summary at the top of this page.
Can I use .300 BLK hollow points for home defense?
.300 Blackout expanding loads are used for home defense; over-penetration is a concern, especially with supersonic loads. Subsonic expanding bullets (Hornady Sub-X) are designed for lower penetration. Suppressed subsonic loads produce a lower report in enclosed spaces.
