Projectile construction

This is a a solid copper design intended for subsonic velocities, where conventional lead hollow points typically fail to open.

It is worth separating weight from construction when comparing loads. They are independent variables, and construction is the one that decides outcome.

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. Published figures are a starting point, not a specification; chronograph your own rifle before you trust a number.

Choosing this bullet weight

At 230 grain this sits at the heavy end of the .45 ACP range. Heavier bullets carry momentum further, buck wind better and penetrate more, and they pay for it with a steeper arc and more felt recoil. If your shots are inside normal hunting distance and you want penetration, this is the end you want.

Pack size

20 rounds at $31.99 works out at $1.599 per round. A box this size suits load development, hunting stock and defensive carry rather than high volume practice.

Compliance

Federal law does not class ammunition as a firearm, yet several states and cities restrict or licence ammunition shipments. You must be of legal age and eligible to possess ammunition at your delivery address. See our shipping and delivery page for the current detail.

Before you trust the box velocity

Velocity scales with barrel length, and the effect is largest on lighter, faster bullets. Check what your own barrel actually delivers. For .45 ACP specifically, expect 830 to 1,000 fps as the published band and treat your own chronograph as the authority.

Choosing .45 ACP over something else

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.

What arrives

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.

Is the solid copper subsonic projectile suitable for what I am shooting?

It is a a solid copper design intended for subsonic velocities, where conventional lead hollow points typically fail to open. Match that against your intended use before buying.

Why choose 230 grain?

Weight sets the trade between velocity and momentum. 230 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.
