Projectile construction

This is a does its work through fluting rather than expansion. The flutes drive fluid outward at high pressure, producing a wound cavity without relying on the bullet deforming, which means performance holds up at lower velocities and through barriers.

The number on the box tells you mass, not behaviour. Jacket design, alloy and geometry are what determine the wound channel.

What 9MM is good at

Standard pressure loads sit near the sound barrier, so subsonic-specific loads matter for suppressed use.

Muzzle velocity for 9mm typically runs 1,000 to 1,250 fps, from a pistol and PCC platform with a 1:10 twist. Barrel length, lot and temperature all move that figure, so verify it in your own rifle rather than relying on the box.

Bullet weight and what it costs you

At 90 grain this is on the lighter side for 9mm. 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.

Cost per round

20 rounds at $29.99 works out at $1.499 per round. A box this size suits load development, hunting stock and defensive carry rather than high volume practice.

Shipping and legal notes

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

Before buying, be honest about the use case. This suits defensive use and barrier performance, where consistent behaviour matters more than expansion, and it works at velocities where hollow points stop opening.

Before you trust the box velocity

Do not assume box velocity applies to your barrel. Published figures usually come from long test barrels, and real rifles run slower. For 9mm specifically, expect 1,000 to 1,250 fps as the published band and treat your own chronograph as the authority.

Storage notes

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 9mm sits

Against .45 ACP it gives up frontal area and gains capacity, flatter trajectory and much cheaper practice. Against .380 ACP it is simply more cartridge in every respect.

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 we ship

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.

A word if you are stocking up: test before you commit. Buying a case of a load your rifle dislikes is an expensive way to learn about harmonics.

Frequently asked questions

What rifle does 9mm run in?

9mm is normally chambered in a pistol and PCC platform with a 1:10 twist. Standard pressure loads sit near the sound barrier, so subsonic-specific loads matter for suppressed use.

How fast does 9mm run?

Around 1,000 to 1,250 fps at the muzzle, though your barrel will give you its own number.

Is the solid copper fluted non-expanding projectile suitable for what I am shooting?

It is a does its work through fluting rather than expansion. The flutes drive fluid outward at high pressure, producing a wound cavity without relying on the bullet deforming, which means performance holds up at lower velocities and through barriers. Match that against your intended use before buying.

Why choose 90 grain?

Weight sets the trade between velocity and momentum. 90 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 $29.99, which is $1.499 per round.

Is this a backorder?

No. This is stocked inventory, not a backorder or a pre-sale.

Are there places you cannot ship ammunition?

Yes. A number of states and municipalities restrict or licence ammunition delivery. Check the shipping page for the current list before ordering.

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 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.

Will this arrive in original packaging?

Yes, in the manufacturer’s packaging, boxed so nothing shifts on the way to you.
