300 Blackout 196gr Solid Copper Subsonic Fracturing Projectiles (Qty 50)

What this is

This is the 300 Blackout 196gr Solid Copper Subsonic Fracturing Projectiles (Qty 50).

This is the 196gr solid copper subsonic fracturing projectile for 300 Blackout, built for the other half of what makes this caliber unusual: running the same rifle quiet and subsonic instead of supersonic.

Why 196gr for subsonic

A subsonic 300 Blackout load has to stay under roughly 1125 fps to avoid the sonic crack a supersonic bullet produces even through a suppressor. At that reduced velocity, a heavier bullet like 196gr retains more energy and momentum than a lighter one would at the same speed, which is why subsonic 300 Blackout loads run considerably heavier than the supersonic 115 to 125gr weights.

Fracturing versus our subsonic expanding option

This is a fracturing design, meaning it is built to fragment on impact and transfer energy quickly rather than penetrate as a single mass. We also stock a 205gr subsonic expanding design that mushrooms instead of fragmenting; choose that one if you want more penetration and this one if rapid energy transfer matters more for what you are shooting.

Frequently asked questions

What makes this a subsonic bullet rather than the lighter 115/125gr options? At 196gr this is heavy enough to stay under the speed of sound (about 1125 fps) even loaded to full case pressure, which is what makes a genuinely quiet suppressed 300 Blackout load possible from the same rifle that also runs supersonic ammunition.

Fracturing or expanding, which subsonic design should I pick? This 196gr is a fracturing design, built to fragment and transfer energy quickly. We also stock a 205gr subsonic expanding design that mushrooms as a single mass instead; pick fracturing for faster energy transfer, expanding for more penetration.

What is a safe subsonic velocity target? Subsonic means staying below roughly 1125 fps at your altitude and temperature. Chronograph your load rather than assuming a book number, since temperature and humidity shift the actual speed of sound on the day you shoot.
