Pro Hunter Bullet Design and Subsonic Performance

The 125-grain Pro Hunter projectile is engineered for controlled expansion when fired from .300 Blackout rifles, particularly in suppressed or unsuppressed subsonic applications. HSM loads these bullets into brass cases that deliver consistent velocity and chamber pressure. Shooters working with specialized firearms should understand California's regulations around certain configurations—resources like PC §32100 exempt revolvers clarify which platforms require additional compliance attention. This ammunition works across standard .300 Blackout bolt-actions and modern sporting rifles. Browse our gun store.
