This meticulously crafted cartridge is designed to deliver a superior shooting experience, characterized by reduced sound signature, mitigated recoil, and unwavering accuracy. For enthusiasts, competitive shooters, or those prioritizing discreet and reliable performance, understanding the specific advantages of this ammunition is key to unlocking the full potential of your .45 ACP firearm.
Why Subsonic .45 ACP Ammunition is Essential for Suppressed Shooting
For anyone utilizing a sound suppressor (silencer) on their .45 ACP pistol or carbine, selecting the right ammunition is paramount. The primary goal of a suppressor is to reduce the sound of the gunshot. However, there's a critical factor often overlooked: the sonic crack.
What is the Sonic Crack?
The sonic crack is a miniature sonic boom created when a projectile exceeds the speed of sound (approximately 1,125 feet per second at sea level, though this varies with temperature and altitude). Even with a highly efficient suppressor, if the bullet breaks the sound barrier, the "crack" it produces will significantly detract from the overall sound reduction. This is why standard velocity ammunition, which often travels above supersonic speeds, can still produce a noticeable crack even when suppressed.
The Subsonic Advantage:
Advanced Armament 28428 ammunition is specifically engineered to stay below the speed of sound. This ensures that the bullet never creates a sonic crack, allowing your suppressor to work at its maximum efficiency. The result is a dramatically quieter shooting experience, making range sessions more enjoyable, reducing ear fatigue, and enhancing the effectiveness of suppressed firearms for tactical or hunting applications where discretion is important. Choosing a quality subsonic round like the AAC 28428 transforms the sound profile of your .45 ACP, making it a true whisper compared to unsuppressed or supersonic counterparts.
Understanding the 230 Grain Flat Nose Enclosed Base (FNEB) Bullet Design
The design of the projectile itself is a critical component of the Advanced Armament 28428's superior performance. The 230 grain weight, combined with the Flat Nose Enclosed Base (FNEB) profile, offers distinct benefits:
The Power of 230 Grains
The 230-grain bullet weight is often considered the classic and most effective standard for .45 ACP. This heavier projectile mass contributes significantly to:
- Consistent Subsonic Performance: A heavier bullet at lower velocities retains more energy and stability, making it inherently easier to keep below the speed of sound without sacrificing terminal performance or accuracy.
- Reduced Felt Recoil: Counterintuitively, a heavier bullet with a slower muzzle velocity can sometimes result in a less sharp, more manageable recoil impulse compared to lighter, faster bullets. This leads to better shot control and quicker follow-up shots.
- Optimal Cycling: Many .45 ACP firearms are designed and tuned to cycle most reliably with 230-grain ammunition, ensuring smooth operation whether suppressed or unsuppressed.
Benefits of the Flat Nose (FN) Profile
The flat nose design, as opposed to a round nose, brings several advantages, particularly for target shooting and range use:
- Clean Punching of Paper Targets: The flat meplat (tip) creates a cleaner, more defined hole in paper targets, making scoring easier and more precise. This is invaluable for competitive shooting and detailed accuracy assessment.
- Consistent Bullet Presentation: For some firearms, the flat nose profile can contribute to reliable feeding from the magazine into the chamber, minimizing malfunctions.
- Energy Transfer (for specific applications): While not designed as a primary self-defense round like a hollow point, the flat nose can offer effective energy transfer on impact for training or plinking, creating a solid and noticeable impact on steel targets.
The Innovation of the Enclosed Base (EB)
The "Enclosed Base" feature is a standout innovation, especially for suppressed shooting. It addresses a common issue associated with traditional lead-based projectiles:
- Elimination of Lead Fouling: Standard ammunition with exposed lead bases can shave off microscopic lead particles as they pass through the barrel and suppressor baffles. Over time, this lead accumulation can degrade suppressor performance, increase maintenance requirements, and expose the shooter to lead particulate.
- Protects Suppressor Longevity: By fully enclosing the lead core within the copper jacket, the AAC 28428 FNEB design prevents lead from being deposited within your valuable suppressor. This significantly extends the life of the suppressor, reduces the frequency and intensity of cleaning required, and maintains peak performance.
- Cleaner Shooting Experience: Less lead fouling means a cleaner firearm overall, reducing the need for extensive post-range cleaning of your pistol and suppressor alike.
