.25 Ackley Magnum (P.O. Ackley Data) |
 |
| Warning! Notes: Standard twist: 10". Special twist: 12", 14". This cartridge is made by necking .300 Magnum cases to .25 calibre and shortening. The capacity of this case is less than most of the .257 Magnum family but still large enough to be badly over bore capacity and thus relatively inefficient. (Handbook for Shooters & Reloaders/Vol. 1 - P.O. Ackley, 1962) NOTE: USE THIS DATA WITH EXTREME CAUTION |
