.30 Ackley Short Magnum No. 1 (P.O. Ackley Data) |
 |
| Warning! Notes: Standard twist: 10". This is one of the shortest if not the shortest .30 Magnum Wildcat cartridges. It is the same as the .270 or 7mm Ackley Magnums except for neck diameter. .30-06 barrels cannot be rechambered for this No. 1 Short .30 Magnum without setting the barrel back one thread. This prevents the accidental firing of .30-06 cartridges. One forming and trimming die is necessary to form cases from .300 Magnum brass. Cases are fire formed and a good stiff load is best for the fireforming step. (Handbook for Shooters & Reloaders/Vol. 1 - P.O. Ackley, 1962) NOTE: USE THIS DATA WITH EXTREME CAUTION |
