57 Subsonic Defense Ammo

57 subsonic defense ammo R57.SD Expanding Subsonic Cartridge from RWS. The R57.SD 57 subsonic defense ammo is a new round that delivers a massive punch and knock down power by causing the round to expand upon impact causing a large wound cavity while remaining slow enough to reduce sound using a suppressor. R&R specializes in 57 subsonic defense ammo and has released its Duty Line specifically for law enforcement to ensure the round does maximum damage to stop any threat that comes your way.

This 57 subsonic defense ammo is a 57 grain Expanding Copper Hollow Point round. It is CNC Machined pure monolithic copper 99.5%. The projectile is a expanding hollow point expanding to 3x original diameter. The penetration is between 13-15 inches.
