Ally Munitions – Canned Ham Series – 300 Blackout 190gr Sub-X®

Canned Ham Series – Quiet, Clean, and Purpose-Built

The Canned Ham Series 300 Blackout 190gr Sub-X was built for shooters who understand what subsonic ammunition is actually designed to do.

This is a short-range subsonic hunting and utility load, purpose-built for suppressed platforms where sound reduction, consistency, and close-range terminal performance matter more than unrealistic velocity claims or long-range expectations.

Subsonic ammunition has limitations—and we believe in being honest about them.

This is not a 500-yard miracle round.
This is a quiet, precision-built tool for practical distances.

A Brief History of 300 Blackout

The 300 Blackout was developed to give the AR-15 platform a true .30-caliber capability while retaining standard magazines and most factory components. Originally designed around suppressed use in short barrels, it quickly became one of the most versatile cartridges available for compact rifles.

Today, it remains the dominant choice for:

• Suppressed shooting
• Short-barrel rifles
• Quiet hunting setups
• Compact defensive platforms

Projectile Details – Hornady 190gr Sub-X®

The Hornady 190gr Sub-X (Subsonic eXpanding) was engineered specifically for subsonic applications.

Unlike traditional heavy bullets that simply punch through targets at low velocity, the Sub-X is designed to reliably expand at subsonic speeds, using a deep hollow-point cavity and specialized internal construction.

• Designed for controlled expansion at low velocity
• Optimized for subsonic terminal performance
• Excellent option for close-range hunting and suppressed applications

This load is ideal for:

• Short-range hog hunting
• Quiet hunting setups
• Precision suppressed shooting

Ballistic Specs

• Caliber: 300 Blackout
• Bullet: Hornady 190gr Sub-X®
• Platform: AR-15 / Bolt Action
• Twist Rate Recommendation: 1:5 – 1:8 preferred
• Optimized Barrel Length: 8"–16"

Velocity Information

This ammunition is loaded to remain subsonic, with velocities generally staying below 1,000 FPS, depending on:

• Barrel length
• Suppressor configuration
• Environmental conditions
• Rifle setup

Subsonic ammunition performance varies greatly from rifle to rifle. Always chronograph your ammunition through your own setup for accurate data.

How These Velocities Are Calculated: Our In-House Ballistic Engine

Every subsonic load we develop is validated through Ally Munitions’ in-house ballistic modeling engine, built around real chronograph testing and platform-specific evaluation.

For this 300 Blackout 190gr Sub-X offering, our model accounts for:

• Barrel-length efficiency in subsonic platforms
• Suppressor influence on velocity consistency
• Temperature sensitivity at low-pressure operating ranges
• Semi-auto cycling behavior
• Subsonic stability across common twist rates
• ±10 FPS spread simulations for real-world SD/ES expectations

Subsonic ammunition is far more sensitive to rifle configuration than traditional supersonic loads. Our goal is not to advertise unrealistic numbers—it is to produce ammunition that remains reliable, quiet, and consistent across real-world setups.

Why Canned Ham Is Different

We didn’t just throw a heavy bullet into a case and call it “subsonic.”

This load was developed through extensive testing focused on solving the most common frustrations shooters experience with subsonic 300 Blackout ammunition.

Key Performance Goals

• Extremely clean-burning operation
• Minimal unburned powder residue
• Low muzzle flash, even in short barrels
• Reliable subsonic performance
• Tight, repeatable groups

Each charge is hand-measured with precision, and every batch is assembled with consistency at the forefront.

Performance Expectations

This is a short-range hunting load.

• Designed for practical engagement distances
• Optimized for suppressed use
• Built around consistency and quiet operation
• Not intended for long-range terminal performance

We will continue developing additional expanding subsonic options in the future, but shooters should always maintain realistic expectations regarding subsonic ballistics and terminal performance.

Suppressor Compatibility

• Optimized for traditional baffled suppressors
• Functions well in most properly tuned semi-auto systems
• Flow-through suppressors have not yet been fully evaluated and may require tuning adjustments

Packaging Options

Our new packaging system is designed around improved protection and long-term storage.

Available in:

• 20 Round Cans
• Sealed protective bag packaging
• Silica gel included for moisture control and long-term storage support

Accuracy & Consistency

In our testing, this load has consistently demonstrated:

• Excellent subsonic consistency
• Very low SD performance
• 1 MOA—or better—accuracy potential at 100 yards in properly configured rifles

Faster twist rates generally produce the best stability with the 190gr Sub-X projectile.

Use & Safety Notes

All Ally Munitions ammunition is handloaded and tested across multiple rifle platforms.

• Ensure your rifle is properly tuned for subsonic cycling
• Barrel length, suppressor design, and gas system configuration will affect reliability
• Always check for pressure signs and proper bullet stabilization
• Use at your own risk and ensure your firearm is in proper working condition

Care & Storage

Store ammunition in a cool, dry place.
Avoid prolonged exposure to heat, sunlight, or humidity.
Silica gel packaging is included to help improve long-term storage stability.

Legal Disclaimer

• You must be 18 years or older to purchase rifle ammunition
• Always confirm your firearm is chambered in 300 Blackout
• All ammunition sales are final
• Know and comply with your local and state laws before ordering
