7mm Improved Arch (P.O. Ackley Data) |
 |
| Warning! Notes: Standard twist: 10". The 7mm Improved Arch is the same cartridge as the 6.5 Arch except it is necked up to accept the larger 7mm bullet. This is another very efficient cartridge especially well adapted for use in short and medium length actions. (Handbook for Shooters & Reloaders/Vol. 1 - P.O. Ackley, 1962) NOTE: USE THIS DATA WITH EXTREME CAUTION |
