.17 Mach III (P.O. Ackley Data) |
 |
| Warning! Notes: Standard twist: 10". This is a .17 calibre cartridge for pistols. It is made by necking down the .221 Remington Fireball and pushing the bottom of the shoulder back to create a 30 degree shoulder in order to produce a neck of more ideal length for handloading. This cartridge was introduced by the O'Brien Rifle Company, and they hold a copyright on the name. (Handbook for Shooters & Reloaders/Vol. 2 - P.O. Ackley, 1966) NOTE: USE THIS DATA WITH EXTREME CAUTION |
