Projectile construction
This is a engineered to break apart in a controlled way on impact, converting velocity into rapid energy transfer rather than pass-through.
The number on the box tells you mass, not behaviour. Jacket design, alloy and geometry are what determine the wound channel.
300 Blackout background
Full powder burn by roughly 9 inches, which is why it dominates short barrel builds.
Muzzle velocity for 300 Blackout typically runs 1,000 fps subsonic, 2,100 to 2,300 fps supersonic, from a AR-15 platform with a 1:7 to 1:8 twist. Barrel length, lot and temperature all move that figure, so verify it in your own rifle rather than relying on the box.
Choosing this bullet weight
At 125 grain this is on the lighter side for 300 Blackout. Lighter bullets leave the muzzle faster and shoot flatter, which helps on smaller targets and at distance, but they bleed velocity sooner and depend more on impact speed to do their job.
What you get for the money
160 rounds at $229.99 works out at $1.437 per round. Bulk packaging like this is how you keep a rifle you shoot regularly fed without the per round cost climbing.
Before you order
Federal law does not class ammunition as a firearm, yet several states and cities restrict or licence ammunition shipments. You must be of legal age and eligible to possess ammunition at your delivery address. See our shipping and delivery page for the current detail.
Intended use
The question is not whether this is a good load, it is whether it is the right one for you. This suits hunters and defensive shooters who want rapid energy transfer and multiple wound paths rather than a single clean channel.
Barrel length and velocity
Barrel length changes the numbers. Short barrels give up velocity that light bullets in particular depend on, so a load that performs from 20 inches may disappoint from 16. For 300 Blackout specifically, expect 1,000 fps subsonic, 2,100 to 2,300 fps supersonic as the published band and treat your own chronograph as the authority.

How 300 Blackout compares
Against 5.56 it gives up range and gains suppressed performance and short barrel efficiency. Against 8.6 Blackout it gives up roughly half the subsonic energy and gains an AR-15 platform and far cheaper ammunition.
Pick the cartridge that fits the shooting you actually do, not the shooting you read about.
Frequently asked questions
What platform suits 300 Blackout?
A AR-15 with a 1:7 to 1:8 twist is the usual setup. Full powder burn by roughly 9 inches, which is why it dominates short barrel builds.
Is the published 300 Blackout velocity accurate?
It is indicative. Expect 1,000 fps subsonic, 2,100 to 2,300 fps supersonic as a range, and verify with a chronograph.
Is the fracturing projectile suitable for what I am shooting?
It is a engineered to break apart in a controlled way on impact, converting velocity into rapid energy transfer rather than pass-through. Match that against your intended use before buying.
Why choose 125 grain?
Weight sets the trade between velocity and momentum. 125 grain is one point on that curve; the right pick depends on your barrel, your distance and your target rather than on the number itself.
What is in the pack?
