The sound level produced by a .17 Hornady Magnum Rimfire (HMR) cartridge, when fired through a firearm equipped with a sound suppressor, is significantly reduced. Suppressors, also known as silencers, work by slowing and cooling expanding gases produced during firing. This reduction in muzzle report can be beneficial in various contexts.
Reduced noise levels offer several advantages, including enhanced hearing protection for shooters, decreased disturbance to surrounding environments, and improved communication among individuals in shooting activities such as hunting or training. Historically, sound suppressors have faced regulatory hurdles and misconceptions, but increasing awareness of their benefits for hearing safety and environmental impact is driving broader adoption.
