Subsonic rounds use heavier bullets to avoid breaking the sound barrier; this lower speed avoids creating a sonic boom and significantly reduces the sound of the firearm, especially when combined with a suppressor. Ear protection should still be used when firing subsonic rounds.
CCI was founded in 1951 by Richard Speer. The company originally specialized in providing primers to reloaders, a business they maintain today along with the sale of market-leading rimfire ammunition.
