What this solid copper fluted non-expanding bullet is built to do
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 45ACP is good at
Naturally subsonic in standard loadings, which makes it one of the easiest cartridges to suppress well.
Muzzle velocity for .45 ACP typically runs 830 to 1,000 fps, from a pistol and pistol carbine platform with a 1:16 twist. Expect real world variation against those figures. A chronograph and ten rounds will tell you more than any spec sheet.
Where this weight sits
At 120 grain this is on the lighter side for .45 ACP. 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 $30.49 works out at $1.524 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.
What your barrel does to these numbers
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 .45 ACP specifically, expect 830 to 1,000 fps as the published band and treat your own chronograph as the authority.

Where .45 ACP sits
Against 9mm it delivers a larger frontal area at lower velocity and naturally subsonic speed, at the cost of magazine capacity and ammunition price.
Cartridge arguments usually come down to people optimising for different things without saying so. Decide what you are optimising for first.
Stock and handling
What ships is sealed factory ammunition, stored indoors and rotated so the oldest stock moves first. Packing is chosen to stop cartridges moving inside the box.

Frequently asked questions
What platform suits .45 ACP?
A pistol and pistol carbine with a 1:16 twist is the usual setup. Naturally subsonic in standard loadings, which makes it one of the easiest cartridges to suppress well.
What velocity should I expect from .45 ACP?
Typically 830 to 1,000 fps. Barrel length, temperature and lot all shift it, so chronograph your own rifle.
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 120 grain?
Weight sets the trade between velocity and momentum. 120 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 $30.49, which is $1.524 per round.
