Effects of Sound Suppressors on Muzzle Velocity, Bullet Yaw and Drag

Abstract

Little has been published regarding whether and how sound suppressors impact bullet flight, including velocity, bullet yaw, and drag. These parameters were compared for four different bullets fired from a .300 Winchester Magnum under four different muzzle conditions (no device and three different suppressors). While effects were not observed in all cases, results indicate that sound suppressors can have the effect of reducing bullet yaw and drag significantly, and can also have small effects on muzzle velocity. Results further suggest that bullets with a propensity to yaw demonstrate significant reductions in yaw and drag when shot through a two stage symmetric suppressor versus unsuppressed or with a conventional mouse-hole/K-baffle design.

Force and Sound Pressure Sensors Used for Modeling the Impact of the Firearm with a Suppressor

“…The silencer and muzzle brake problems are most often addressed in the scientific literature: impact on bullet trajectory [77][78][79], effects of sound pressure generated during the shot on hearing [80][81][82][83][84][85], and reducing the sound pressure of firearms by using various types of silencers [86][87][88]. However, problems related to the use of the device for recreational use are not addressed.…”
