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.

Working with 45ACP

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. 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 135 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 and cost per round

20 rounds at $30.99 works out at $1.549 per round. A box this size suits load development, hunting stock and defensive carry rather than high volume practice.

Before you order

Ammunition is not a firearm under federal law, but shipping is restricted in a number of states and municipalities, and some require a licence or an approved recipient. Buyers must be of legal age and legally permitted to possess ammunition where they live. See our shipping and delivery page for the current detail.

Who should buy this

Loads are tools, not rankings. This suits defensive use and barrier performance, where consistent behaviour matters more than expansion, and it works at velocities where hollow points stop opening.

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 .45 ACP specifically, expect 830 to 1,000 fps as the published band and treat your own chronograph as the authority.

Keeping it serviceable

Keep cartridges cool, dry and at stable temperature. Heat cycling in a garage or vehicle does more damage over time than age does, and factory packaging protects bullet tips from knocking together.

.45 ACP against the alternatives

Against 9mm it delivers a larger frontal area at lower velocity and naturally subsonic speed, at the cost of magazine capacity and ammunition price.

Pick the cartridge that fits the shooting you actually do, not the shooting you read about.

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.

If this is your first purchase in this calibre, buy one box before you buy ten. Rifles are individual, and a load that groups beautifully in one barrel can string in another for no obvious reason.

Frequently asked questions

Which twist rate does .45 ACP need?

1:16 is standard. 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 135 grain?

Weight sets the trade between velocity and momentum. 135 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 $30.99, which is $1.549 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.

Do I need a licence to buy this?

In most of the country no, but some states and cities require a licence or an approved recipient for ammunition. The shipping page has the detail.

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 offer bulk pricing?

Larger pack sizes carry a lower cost per round, which is listed on each product page so you can compare directly rather than doing the arithmetic yourself.

Do you sell remanufactured ammunition?

No. Everything listed is sealed factory ammunition.
