8mm-06 / 8mm-06 Ackley Improved Reloading Data

Load Image
Warning! Notes: Standard twist: 12". The 8mm-06 is made by simply necking up the standard .30-06 case to accept the 8mm (.323) bullet. Standard 8mm barrels can easily be rechambered for the 8mm-06 and the magazines lengthened slightly to handle the longest bullets, thus creating a rifle that is certainly the equal of the .30-06 and most likely one which is more effective for the larger types of big game. Standard twist: 12". 8mm-06 Ackley Improved - This cartridge is simply the Ackley Improved 06 necked up to 8mm and is even better than the very fine standard 8mm-06. It is especially good for the heavier bullets from 170 gr. up. Since the 8mm-06 is a handloading proposition anyway, it would seem that the Improved version would be the better choice. It should be as effective on all species of big game as the standard .300 Magnum. Use loading data for the standard 8mm-06, increase 5%. (Handbook for Shooters & Reloaders/Vol. 1 - P.O. Ackley, 1962) NOTE: USE THIS DATA WITH EXTREME CAUTION
