Projectile construction
This is a a solid copper hollow point that opens into petals and retains close to all of its weight, which makes it legal in lead-free jurisdictions and reliable through intermediate barriers.
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. Expect real world variation against those figures. A chronograph and ten rounds will tell you more than any spec sheet.
Bullet weight and what it costs you
At 110 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
20 rounds at $39.99 works out at $2.000 per round. A box this size suits load development, hunting stock and defensive carry rather than high volume practice.
Compliance
Ammunition ships within the United States subject to state and municipal restriction. Some jurisdictions require licensing or prohibit delivery outright, and buyers must meet age and eligibility requirements where they live. See our shipping and delivery page for the current detail.
Intended use
Match the load to the job rather than the price. This suits hunting where weight retention and reliable expansion matter, including lead-free jurisdictions.
Barrel length matters
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 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.

Where 300 Blackout sits
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.
None of that makes one cartridge better in the abstract. It makes them better at different jobs, and the job is yours to define.
What arrives
We stock factory loaded ammunition only, no remanufactured or reloaded product. Stock is stored indoors, rotated oldest first, and packed to keep projectiles protected on the way to you.
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
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.
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 monolithic copper expanding projectile suitable for what I am shooting?
It is a a solid copper hollow point that opens into petals and retains close to all of its weight, which makes it legal in lead-free jurisdictions and reliable through intermediate barriers. Match that against your intended use before buying.
Why choose 110 grain?
Weight sets the trade between velocity and momentum. 110 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 $39.99, which is $2.000 per round.
Is this load in stock?
Yes. Everything on this page is held in stock and ships from the United States. Sold out lines are updated rather than left live.
Can you ship this to my state?
In most cases yes, though several states and cities restrict ammunition shipments or require a licence. Our shipping page lists current restrictions.
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.
Can I reload this brass?
Most of our loaded ammunition uses reloadable boxer primed brass. Check the individual listing if you intend to reload, since some training and steel cased lines are not reloadable.
Do you sell remanufactured ammunition?
No. Everything listed is sealed factory ammunition.
