Bullet Drop: Supersonic 300 Blackout VS Subsonic 300 Blackout | Palmetto State Armory

This discussion from Regular Guy Training LLC delves into the practical applications and limitations of the 300 Blackout cartridge, particularly in civilian contexts. The panel of firearms instructors and enthusiasts argues that while 300 Blackout was designed for specific military roles, its civilian utility is questionable due to reliability issues, high cost, and a lack of distinct advantages over other calibers. They emphasize that a 'fighting rifle' must be reliable, accurate, and durable, qualities they find lacking in many 300 Blackout platforms when pushed to their limits. The conversation also explores the concept of a Personal Defense Weapon (PDW) and why 300 Blackout often falls short of meeting those requirements.

This guide, presented by a Palmetto State Armory representative, demonstrates the audible and visual differences between supersonic and subsonic 300 Blackout ammunition when fired from a suppressed AR-15. It highlights that subsonic rounds eliminate the sonic crack, offering superior noise reduction for suppressed systems. The principles discussed are applicable to other calibers like 9mm.

This video debunks common firearm myths with practical demonstrations. It clarifies that suppressors do not make firearms silent but significantly reduce noise and recoil. The demonstration shows heavier bullets provide more knockdown power at closer ranges, while lighter, faster bullets with better ballistic coefficients are superior for long-range accuracy. The video also illustrates that barrel length does not inherently dictate accuracy, with caliber and ammunition quality being more critical factors for certain platforms like the 350 Legend. Finally, it concludes that rifle weight (heavy vs. light barrel) has a less significant impact on accuracy than ammunition and barrel quality, especially under varying environmental conditions.

This guide, presented by an experienced instructor from Palmetto State Armory, details how barrel twist rate significantly impacts .300 Blackout ammunition stability. It explains that faster twists (1:5) are ideal for heavier subsonic rounds, while slower twists (1:7) are better for lighter supersonic rounds. The video demonstrates live-fire testing to illustrate these performance differences, aiding shooters in selecting the appropriate barrel for their preferred ammunition type.

This video demonstrates the audible difference between supersonic and subsonic 5.7x28mm ammunition when fired from a suppressed firearm outdoors. The speaker highlights the muffled sound of suppressed fire, implying the use of subsonic rounds for maximum noise reduction. Visuals clearly label the two types of ammunition for comparison.

Sully from Line 45 outlines seven essential calibers for gun owners to stockpile in anticipation of future ammunition shortages, emphasizing their specific roles and the current market conditions. The video highlights the importance of proactive stocking for calibers like 300 Blackout, 308 Winchester, 10mm Auto, 12 Gauge, 22 LR, 223 Remington/5.56 NATO, and 9mm Luger, detailing their performance characteristics and availability challenges.
