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.
Bullet weight and bullet construction get conflated constantly. Weight sets trajectory and momentum; construction sets what happens on impact.
What 300 BLACKOUT is good at
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 115 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.
Pack size and cost per round
20 rounds at $38.99 works out at $1.950 per round. A box this size suits load development, hunting stock and defensive carry rather than high volume practice.
Compliance
Shipping rules for ammunition vary by state and sometimes by city. Some destinations require a licence, an approved recipient, or refuse delivery entirely. Check before you order rather than after. See our shipping and delivery page for the current detail.
Who should buy this
Before buying, be honest about the use case. This suits hunters and defensive shooters who want rapid energy transfer and multiple wound paths rather than a single clean channel.
What your barrel does to these numbers
Do not assume box velocity applies to your barrel. Published figures usually come from long test barrels, and real rifles run slower. 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 to store this
Ammunition stores for decades if you keep moisture and temperature swings away from it. Sealed containers with a desiccant pack beat an open box in a shed every time.

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.
How this is stored
This is genuine factory ammunition, held in a climate stable stockroom rather than a container. Orders are picked from sealed cases and packed so nothing shifts in transit.
Test one box before buying in quantity. Two rifles of the same model can prefer different loads, and there is no way to predict which from a spec sheet.
Frequently asked questions
Which twist rate does 300 Blackout need?
1:7 to 1:8 is standard. Full powder burn by roughly 9 inches, which is why it dominates short barrel builds.
What velocity should I expect from 300 Blackout?
Typically 1,000 fps subsonic, 2,100 to 2,300 fps supersonic. Barrel length, temperature and lot all shift it, so chronograph your own rifle.
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 115 grain?
Weight sets the trade between velocity and momentum. 115 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?
20 rounds at $38.99, which is $1.950 per round.
How quickly does this ship?
It is in stock and ships from the United States. Processing times and carrier detail are on the shipping page.
What are the delivery restrictions?
They vary by state and sometimes by city, ranging from licensing requirements to outright prohibition. See the shipping page.
How should I compare loads?
Compare cost per round rather than box price, and compare projectile construction rather than grain weight. Those two habits will steer you right more often than brand loyalty.
Do you sell components for this cartridge?
We stock projectiles and brass for several of our calibres alongside loaded ammunition. Check the projectiles and brass category for what is currently available.
Do you sell remanufactured ammunition?
No. Everything listed is sealed factory ammunition.
