The Truth About Guns highlighted the 375 Raptor in its Silencer Saturday series as a niche option for suppressed mid-bore rifles. The round enlarges a 308 Winchester case to fire .375-inch bullets, enabling subsonic loads of 350 to 400 grains that remain below the speed of sound while delivering extra mass for energy. Supersonic versions also exist, such as a 235-grain projectile near 2400 feet per second that roughly matches a reduced-recoil 375 H&H yet fits ordinary short-action rifles. Unlike 300 Blackout or 8.6 Blackout, the cartridge is not SAAMI-standardized, so major manufacturers skip it and only boutique loaders supply factory ammo, making reloading the practical route for most owners. Larger 46-caliber suppressors are usually required because typical 36-caliber cans may not clear the bigger projectile.
