Sav,

I did a little nosing around and see from the ADI website that this new powder is similar to Vit. 24N41, Re-25 and Retumbo.

Some loads:

Without direct data for your ADI powder, you will have to do a little interpolation. That's why I included the Retumbo loads from Hodgdon. Just do what always gets suggested and start a bit low and work up slowly.

My other suggestion would be to contact ADI and ask them about suggested starting data. If they are like any of the other powder manufacturers, they will bend over backwards to lend a hand.

Regards.
