The .17 MACH IV Cartridge - Out of Sight – but Is It Out of Mind?

The smallest I've gone is the .204 Ruger.

The .17 Mach IV was created in 1962 by Vern O’ Brien in Las Vegas, Nevada, a company specializing in high-quality “custom-production” rifles. Using the recently introduced .221 Remington Fireball case as his base, he opened up the shoulder from the host 23 degrees to 30 degrees and necked it down to .172 caliber while keeping the same overall case dimensions. O’Brien sold his company to Harrington & Richardson and they developed the .17-223, which later became the .17 Remington.
