Anyone got experience loading the 9.3x57 in a commercial 98 action with ADI (Australian) powders? Cheers,Charlie.

A bloke on another sight told me to start at 80% and work up to a maximum of 86% of 9.3x62 loads.
How safe this is I do not know, if you try the above, you do so at your own discretion.
Good luck.

From the ADI handbook, 3rd edition.

They list AR 2206, and AR 2208.
The 250 gr load is a max of 41.5 of 2206, and 45 of 2208.
Please note that these are MAXIMUM loads. As such, I would reduce these by 10% and start up from there.

Best of luck.

Thanks guys, much appreciated. I've tracked down a few other suggestions from 'Googling'. Charlie.
