Thread: 30-06 Akley improved load development

Greetings @dannyb,
I remembered that there was an article in Handloader and dug it out. Gil Sengel did an in depth article in 1986 in issue 123 of Handloader Mag. He worked up loads using case head expansion to estimate pressure for both the .30-06 and its AI cousin. He used the same barrel and throat to reduce variation. One of the powders used was IMR4350 which is very close in speed to current AR2209. The increase in velocity for the AI was modest generally 50 fps or less which is about what you would expect from the small increase in case capacity.
For the 165 grain he loaded 60.5 grains of IMR4350 for 2,955 fps and for the 180 grain 59.5 grains of IMR4350 for 2,820 fps.
Regards Grandpamac.
